Prospectus Idol Entry

Are Offensive Shortstops Becoming Toxic Sub-Prime Mortgages and Other Evolutionary Trends in Baseball Positions

by Tim Kniker

In March 2002, Baseball Digest said we were living in "the era of the shortstop." After all, the late 1990s ushered in a crop of offensive-minded shortstops like Alex Rodriguez, Miguel Tejada, Derek Jeter, and Nomar Garciaparra. The article included the Royals' Neifi Perez, but given the benefit of hindsight, I'll leave him out of the discussion. A popular conception was that this represented a new era where the once defense-dominated position was no longer going to be a wasted spot in the batting order. As the other teams scrambled to keep up with the Joneses, was something lost in the process? Is the quest for the next batch of power-hitting shortstops leaving defense in its wake? To answer this question and others, we will use the Win Shares system to help us.

Our Data Workbench: The Win Shares System

In 2002, Bill James published his book on Win Shares, which the dust jacket claimed was "a revolutionary system ... for player evaluation." For those readers who are not familiar with it, the Win Shares system allocates a portion of each team's wins for the season to each player based on his statistical performance. These Win Shares are categorized into three groups: batting/base-running, fielding, and pitching. For a more detailed description (and believe me, it is detailed as James needs about 100 pages to describe all the mechanics) the reader can either buy the book or use one of the following on-line articles as a jumping-off point: Tom Tango's website, Wikipedia, or BaseballGraphs.com.

While the objective of this article is not to debate the efficacy and accuracy of this metric, the reader should be aware that there were some initial criticisms. With that said, the folks at BaseballGraphs and The Hardball Times have made refinements to the calculations to resolve many of these issues. The data that I used in this article was downloaded from the BaseballGraphs website and gives the Win Shares for each player-team-year combination from 1900 to 2008.

Since fielding Win Shares are key to this article's analysis, it should be noted that one of the main criticisms is how the Win Shares methodology addresses fielding. Much of the criticism is that it doesn't use the more advanced defensive metrics that have been developed in the last few years. Some of its fielding calculation simplicity is because games from the early twentieth century lack the play-by-play data of the Retrosheet era (1954 - present) and the consistent batted ball information (1989 - present) from recent games. James wanted to have a system that could use readily available statistics and go as far back into history as possible. Current independent research by Colin Wyers uses some probabilistic modeling to allocate the uncharted hits to improve the approximation of the average number of hits in aggregate that should be assigned to a given fielder, and will still allow fielding statistic calculations as far back as 1871. As this methodology gets refined and potentially incorporated into the Win Shares calculations, it will be interesting to see if the allocated fielding shares change significantly.

Typically the focus of Win Shares has been on the value of a given player relative to others. As I started looking at the data, I became more interested in looking at Win Shares in aggregate to see how the game (and more specifically, each individual position) has evolved.

The (De-)Evolution of the Middle Infielder

What have baseball teams expected from each position in terms of the trade-off between offense and fielding and has this changed through the years? To address this question, I plotted the percentage of that position's Win Shares that come from fielding versus its total Win Shares over the last 11 decades.

graph

To no one's surprise the positions up the middle (C, 2B, SS, CF) have a higher percentage of their value in fielding as compared to the corner positions (1B, LF, RF). One does see the transformation of third base from a significantly defensive position to the more offensive position it is today. It seems that this switch started in the 1930s and was completed by the 1950s.

By standard variability metrics (standard deviation, range of high to low), the middle infielder, especially the shortstop, has seen the greatest fluctuation (mathematically) in how they contribute to a team's winning. One sees a potential golden age of shortstop defense in the 1970s. For the first time since catchers at the turn of a century, over half the value of a position came from the glove instead of the bat. Wyers' data suggest that the under-appreciated Mark Belanger, the prototypical 1970s' shortstop, was the fielding equal of the consensus defensive wizard, Ozzie Smith. The current Win Shares methodology though has him the fifth best defensive shortstop since 1960 behind Smith, Dave Concepcion, Cal Ripken, and Omar Vizquel.

The new era of the offensive shortstop began in the early eighties with Robin Yount, Ripken and Alan Trammell (all solid defenders), with the first two winning back-to-back AL MVP awards and leading their team to the World Series in 1982 and 1983, respectively. Despite the steady increase in the shortstop's value from his bat in the 1980s and 1990s, it was still primarily a defensive position (45% average value from fielding) as compared to the expectations in the 1930s to 1960s (42% average value from fielding). It's in the 2000s that teams truly pushed the envelope on a shortstop's offensive production to a level of importance that hadn't been witnessed since the turn of the century.

On the other side of the bag, we see a similar but much more gradual trend with second basemen. Their defensive peak came in the 1960s and 1970s, only to see the emphasis shift back to offense again in the 1980s with the emergence of players like Ryne Sandberg, Lou Whitaker, and Willie Randolph and continue through the 1990s and 2000s with Roberto Alomar, Craig Biggio, and Jeff Kent. At this time, one has to consider the question of causation. Are these curves of the middle infielder shaped because that was the type of talent that was available at the time, or was it a change in how the position was valued? To help us address this question, let's consider the value of a given position relative to the rest of the team.

A Position's Value to the Team

The graph below is a plot of the percentage of each position's Win Shares as compared to the total Win Shares of the team (for legibility I have limited it to just 1B, SS, CF, and the maximum of the corner OF spots).

graph

Our Golden Age of Shortstop Defense seems like a misinterpretation of the initial data. Given that there are eight positions, our expectation is that, on average if we assume equal importance, each position should garner roughly 12.5% of a team's Win Shares (the thick black "Equal Value" line). It's a little less starting in 1973 to reflect the inclusion of the designated hitter as a position player. Except for the 1900s, the shortstop has always been less than this "equal-value" point, and hit its ultimate low in the 1970s, as shortstops accounted for only 9.1% of the team's position player value, the lowest point of any position by a long shot. The return of the offensive shortstop was the correct move as an overemphasis on defense was causing the shortstop position to become irrelevant.

There are two other interesting trends that emerge, both related to power. As the game historically switched from triples to home runs, we see the decline of the center fielder and the emergence of the first baseman. The first baseman peak of the 1930s is essentially caused by just two exceptional players in that decade (Lou Gehrig and Jimmie Foxx). From the 1900s to the 1920s, the average team got most of its value from its centerfielder. From the 1930s to 1960s, the centerfielder was still second in value as the corner outfielder reigned as the preeminent value position. Only in the last twenty years has the first baseman dominated all other positions. In general, the catcher (11.3%), second baseman (11.5%) and third baseman (11.8%) have all held pretty steady as to the percentage of team value from these positions, only varying by a few tenths of a percentage from this average in any decade.

Has the Pendulum Swung Too Far?

The return of the offensive shortstop was a solid evolutionary move as the pendulum had placed significant emphasis on defense in the 1970s, but is it in danger of going too far the other way? Let's plot the percentage of a team's batting Win Shares and fielding Win Shares that are claimed by the shortstop.

graph

It is now clear that the 1970s weren't such the defensive golden age as we initially thought. If they were, we would expect to see an increase in the fielding Win Shares claimed by shortstops in the 1970s. In fact, we actually see a decrease from the previous four decades. The spike of the 1970s that we saw in the first chart was caused by the offensive futility of the shortstops of the decade. Why this dearth of shortstops who could hit? Was it just luck, or something programmatic? Beyond the luck explanation, I offer two possible theories:

  • With the rule changes that favored the hitters in the late sixties, baseball teams felt they needed better defense up the middle, and rightly or wrongly, some capable defenders with solid bats were moved off of the position in favor of similarly capable defenders with little bat (Belanger, Freddie Patek, Bucky Dent, and Larry Bowa). With the lack of proper defensive metrics at the time, maybe they just seemed better defenders because of their glove's relative superiority to their bat.

  • Players and scouts will reflect on the recent past and use those as models. So the shortstops of the seventies were modeled on the top shortstops of the sixties like Luis Aparicio, Dick Groat, Maury Wills, and Zoilo Versalles, the latter being another AL MVP shortstop who lead his team to the World Series.

From the 1900s to the 1990s, the shortstop had usually garnered 18.2% of a team's fielding Win Shares. This was always the case within a few tenths of a percent. As teams began to realize the offensive black-hole of shortstops that occurred in the 1970s, a break from the past occurred and more emphasis began to be placed on the need for production out of the position. If one looks at the great batch of offensive shortstops of the 1980s and 1990s, their fielding win-shares were just as solid as their counterparts.

Since the batch of offensive shortstops from the 1990s provided such a competitive advantage to their clubs, other teams followed suit. Unfortunately, there just aren't enough offensive shortstops that are also good defenders out there to meet the demand, so teams began lowering the defensive requirements. For the first time in the history of the game, we have begun to see a significant decline in shortstop fielding, as they only captured 16.2% of their team's fielding Win Shares, a 10% decrease from the previous decade's 17.9%. Keep in mind that this decline in defense is partially due to shortstops that fit the new offensive-first mold (Jimmy Rollins and Jose Reyes), but also results from the initial 1990s crew that saw their defensive abilities decline but weren't moved because of their perceived offensive value at a premium defensive position (Derek Jeter and Nomar Garciaparra).

So how does this relate to sub-prime mortgages? I'll use a gross over-simplification of the global credit crunch to illustrate. Having a few sub-prime mortgages, which have both higher reward and higher risk, can be a good thing, as the basics of portfolio optimization will tell you. However, as banks needed higher levels of return to compete for the consumer's assets dollars, they moved more assets into the higher return sub-prime vehicles, and therefore needed more sub-prime loans. To increase the supply pool of candidate sub-prime loans, they needed to lower the requirements bar (thus increasing the level of risk) for future loans. In much the same way, baseball teams in the 2000s lowered the defensive ability bar in order to increase the supply of offensive shortstops. If teams want (or feel a need) to further increase the supply pool of offensive shortstops, we should expect to see further degradation in the fielding Win Shares that shortstops claim in the coming decade.

Given that the shortstop in the 2000s is still below his "equal-value" point as compared to the other positions and the percentage of total Win Shares captured by shortstops increased in the 2000s, this has been a favorable move. Up to this point, the overall benefit (improved offense) has outweighed the loss (decreased defense). Some in the industry sense getting close to the tipping point. One can look at two of many examples:

However, if the trend continues, you'll want to prepare your kids for the following analogy question on the SAT in 2022:

23. Banks : Sub-Prime Mortgages :: Baseball Teams :
 a) Stadium financing
 b) Offensive shortstops
 c) Contracts lasting more than five years
 d) Empty relish dispensers in the concession stands

The correct answer may be (b).

I think there's something there -- I think the evolution of what I usually refer to as 'offensive expectations' is a great subject, and I don't think any position has changed more than shortstop. Still, I end up thinking about this the same way I thought about Matt's piece, where the concept impressed more than the execution.

While we're going with analogies, using Win Shares to do baseball analysis is like using a rock to drive in a nail - it'll sort of work, but it's not a particularly good idea. With the avalanche of good fielding data and methodology, using the Win Shares fielding metrics is just a disaster. Even if you use better data, the methodology outlined in Win Shares is wholly meritless.

This is probably me just being knowledgeable about enough of the research (or the lack of a good central storehouse), but could you tell me the great fielding data that you have before 1954? As reading Colin, it seems that that is a new area of research to do our best with what we have.

I guess this was a miss with win shares, and while I know some people don't like them, I didn't realize the vehemence that others like yourself have.

It kind of has me wondering if they are so bad, then why does BaseballGraphs and Hardball Times bother calculating them year in and year out?

I've read every entry for every week and this was the first time I've been moved to comment. Absolutely first rate work. One of the best pieces I've read on BP all year. While win shares as a metric may be very flawed, the use of it to measure percentage of value from each position over time coming from offense vs defense was brilliant in its simplicity. Really, really interesting findings, Tim.

The use of Win Shares leaves me baffled. At this point I'm just echoing the same concerns as others, but why spend so much of the article making a case for the use of Win Shares when so many other metrics would make do.

I sort of liked the idea, but I didn't really like the presentation. It seemed the first half of the article included caveats of Win Shares, and though better metrics are referenced, Win Shares ends up being used anyways.

I also think the analysis is a bit off or incomplete at times. For example "As the game historically switched from triples to home runs, we see the decline of the center fielder and the emergence of the first baseman." Based on the chart and the way the CF numbers drip from 1960 to 1970, I thought that it was because Mickey Mantle and Willie Mays retired... but maybe two players didn't have as much of an effect? Then I read " The first baseman peak of the 1930s is essentially caused by just two exceptional players in that decade (Lou Gehrig and Jimmie Foxx)." Also, when I see that kind of a chart with just one data point for each decade, I wonder if there's a "Mark Grace had the most hits in the 1990's" sampling issue.

Also, with all the discussion of the Golden Age of Shortstop Defense, we never get a raw statistic or number quantifying defensive performance... just a percentage. Tim writes, "If they were, we would expect to see an increase in the fielding Win Shares claimed by shortstops in the 1970s." but that is in reference to a chart with percentages labeled "Shortstop's % of Total Team Win Shares". From my perspective, there is a chance that shortstops were better fielders, but their hitting was so much worse that it lowered their overall contribution... or maybe the other positions on the diamond got better, reducing the shortstop's percentage.

The subprime part felt really tacked on to give the article some sense of structure. That it was introduced so abruptly with no warning, besides the title, made me backtrack over the article to wonder where else subprime had been mentioned.

I realize that Win Shares were used because there is more historical information there... but even if I accept that there are flaws for using that system, I still am unconvinced of much of the conclusions presented.

Tim had a good idea, but this is the first week I've read from him where I ended up scratching my head... and not because I couldn't understand it, but because the information and conclusions I saw did not fit together logically for me.

That being said, easy thumbs up based on prior weeks.

Thanks for posting the missing paragraph, Richard. When I load this page, I get the sentence:

"As the game historically switched Lou Gehrig and Jimmie Foxx)."

That aside, I think Steven Goldman nailed the criticisms. Great idea, but wandered off into a swamp and sank. I really missed the paragraph discussing what the distribution of contribution among the positions *should* be, and why. "All equal" isn't obvious. And, as Richard notes, there are some "relative contribution vs. absolute contribution" issues, both among positions and between offense and defense, that were not handled cleanly.

Content B- - I found the graphs and data interesting. I don't think Win Shares are a perfect stat, but it was adequate enough to show the trends Tim tried to show. It didn't take me two seconds to realize that the percent of a shortstop's value peaking around 1970 was due to their being a lack of offensive shortstops around then. His next graph merely confirmed it. I'll agree with Stephen, this would have been much better with more historical depth rather than relying on this thin statistical analysis.

Writing B+ - I never have any problem following Tim. He speaks my language with joyful wink. However, I have to agree with Christina, the sub-prime mortgage comparison was a little too silly and wasn't even an accurate one. The banks were not only changing the balance of risk vs. reward, but as Tim noted, they were changing the rules at the same time. Choosing a shortstop in these cases is simply balancing offense and defense.

I liked the analysis, but as I'm an actuary, I wonder if this is a case of well put together analysis on crummy data leading us to a conclusion we just don't know if we can trust.

I'm with Tim. I don't get why people hate Win Shares so much. To me, this seems like the perfect place to use them, because you can compare the proportion of a player's offensive value to his defensive value, across historical eras, with much more accuracy than with other tools (such as WAR or PBP-based metrics, which are really only good for the past few years, as far as I can tell).

I would agree that the conclusion seemed to be forced to fit the title, but was not particularly supported by the evidence as I understood it.

I think that one of the points all the critics of Win Shares miss is that the analysis is all relative. While I might correctly disregard any conclusion that Maury Wills was worth X wins more or less than Carl Ripken, I can probably be reasonably confident in a conclusion that Wills contributed less to the Dodgers' success than did Ripken. Any number of metrics can be flawed, but if they're used in a consistent fashion to draw relative conclusions, they can be a source of insight.
I'm not sure what to make of Will Carroll's criticism of the flow of the writing. This article moved right along for me, with the charts supporting the words.

The topic is interesting but I don't think it was a good choice given this week's assignment. The inability to bring it to the present by referencing the decline of the Trinity and our current environment of HanRam and the 29 Dwarfs was too restrictive. Is the fact that he mentioned a few active shortstops in the last third of the article considered 'cheating' or was it just a reflection of being hamstrung by the restrictions? I voted thumbs down on this one.

I too have little or no use for Win Shares, and I enjoy THT and BG despite those feelings. When I first started reading, I thought, "Oh no, NOT Win Shares! This could be bad."

It wasn't. I'm not sure I trust the data, but it was an interesting topic and, concerns about Win Shares' accuracy aside, a fascinating approach given the metric. Tim's already shown that he's a great writer. For me, Steven's comment about wasting 400 words on Win Shares just shows how important a great editor is to the writing process, too.

I much prefer Clay Davenport's WARP3 for comparing across eras, even given that FRAA/FRAR, like all defensive metrics, have some issues. I'd like to see the results if Tim used BRAR and FRAR instead of Win Shares.

Agreed. Let me reiterate that even had Tim used a better metric, it likely wouldn't have changed the directional conclusion regarding shortstops (and other positional trends embedded in the graphs). Let's not lose the forest for the trees here.

And while I'm here, let me just add that I've seen enough from Tim and Matt S to know that I'd like to see both of them become regular contributers here -- regardless of who wins. There are a few other competitors who are turning in BP-worthy material on a regular basis as well.

So, let me round up some of the comments/critiques into one.

1) Too many words on Win Shares debate: This is where I may (or may not) be taking some of Will's comments to heart, or still just have a bit of a stuck gear in "The Basics" topic from a few weeks ago. Personally, before I started this, I had no idea of whether Win Shares are good/bad, feelings, so I put some words on things that I learn in the week as I do these articles. It seems that I haven't found that magic window of when to explain something to the less-stat savvy BP readers and when to just leave them behind. Sometimes there's a bit of a damned if you do, damned if you don't on this. I guess I wasn't trying to spark a debate, so much as bring an uneducated reader quickly up to the table of the debate -- seems people don't like this AT ALL.

2) Actual selection of Win Shares: Win Shares aren't perfect, but then no statistic is. My goal with Win Shares is that they met two criteria:

a) They go back a relatively long way
b) They put pitching, fielding, & hitting on the same scale.

Could someone direct me to a single number that does?

I view my use of Win Shares like Newtonian mechanics. Sure it's horrible if you're trying to do things in the Quantum world, but it works pretty well if you're figuring out the forces on an airplane.

3) Win-Share percentage: To address Christina's point of 3-5 win shares are meaningless, except that given we are talking about a decade at a time and a whole slew of players, the shortstops in the 1970s had 1631 shares of batting and 1681 of fielding, so I think the overall trends aren't meaningless and there is enough to drive high-level trends

4) Trying to be too cute on Sub-prime, etc.: I guess it's one of those things that either you got it (Ken) or you don't. It seems that every time I try to make something more interesting it doesn't work out, so maybe I should go back to being a little dry with my ocassional natural quip here and there and let the chips fall where they may.

The subprime analogy is apt (you could use any bubble for your analogy.)

IMO, it was a cute joke...until you had to explain it. And if you didn't explain it, I suppose most readers wouldn't have known what you meant. Probably should have found a more accessible analogy or left it out. 162-word explanations of jokes are no fun.

It's tough trying to find the right balances (explain or not to explain) (joke or not to joke). Overall you are doing great.

I wasn't annoyed by your Win Share explanation.

The sub-prime thing was kinda funny - and I appreciate a bit of levity. "Too cute" and "silly" are better than dry and boring. Humor is very personal and certainly not an exact science. Perhaps, it was just that it seemed a little forced. As I said before, it doesn't quite work in my view. You have a good sense of humor, Tim. I am just trying to encourage you to do a little better.

To add to Christina's comment - reducing everything to % may obscure some of these trends. Maybe the bigger change over the past 20 years is that teams have started to take 1B and corner OF defense more seriously, so the % of fielding runs from SS has dropped while the absolute level has held steady. Or not - can't tell.

And what's with the arbitrary decade stuff? Why not give us a moving average? Or break it into periods that purport to define these "eras" of shortstopness.

I really like the article, in all. A solid jumping off point.

"Maybe the bigger change over the past 20 years is that teams have started to take 1B and corner OF defense more seriously, so the % of fielding runs from SS has dropped while the absolute level has held steady. Or not - can't tell."

Maybe this is one of the problems that one has with Win Shares. The problem is that given there is a number of games played in a given decade (or year), etc, there will be an exact number of Win-Shares. The question is how those wins are divided, and unless we see that there is a huge change in DER, from decade to decade there is a pretty consistent % of Win-Shares that are given for fielding.

I guess it's my trust in the data, that essentially if in past it's been surprisingly consistent that the shortstop has been capturing 18% of the Win Shares and then immediately drops down to 16%, while there's an incremental rise in all other positions across the board, that this seems to me evidence that the shortstop fielding has gone down, as opposed to every other position has seen a slight rise in fielding.

Thanks for clarifying - I had forgotten about the zero-sum game of Win Shars.

That's pretty much the problem with Win Shares.

It's a zero sum game league wide, but not team-wide. The percentages aren't as useful when they are being compared to other players on the same team since a team with a better win-loss record would have more win shares than a team without. In other words, I can't tell if a shortstop that accumulated 10% of a team's win shares accumulated 6 win shares, 8 or 10... since I don't know how many win shares the actual team got.

Richard, yes but at the end of the day, what I'm comparing essentially is all shortstops compared to all teams, so these work themselves out.

As an example, for a given team it's not uncommon to have a shortstop gain 25% - 30% of the fielding win shares over the course of a decade. The thing I found interesting is that in any given year is that this number really hovers around 17.6% - 18.7% leauge-wide for a shortstop, and then BAM! 16% down to one year a low of 15.6%

If league-wide defense improves as a whole, though, doesn't it make it harder to interpret the percentages? I doubt that a 17.6%-18.7% shortstop from the 1920s is as good of a fielder as a 17.6%-18.7% shortstop from today.

So, when "BAM" the percentage goes down one decade (and by your data points, you're referencing one year of a specific decade), is it because some great shortstops retired, or some other positions got better? It might be more convincing if there were multiple years in the 1970s that showed the downturn, but with just one down year, there could be other explanations.

One thing I'm wondering about (and it'll be interesting to hear from the readers) is not only on mine, but the others, is your general impressions of the article's "bite size."

There's no question that a lot of comments on many of mine and other contestants articles are about what was left out or should have been put in. I think the hardest thing about the competition for me is given a theme, than in just 3 days (and it will actually be 24 hours this week as a "test") we have to research, write, etc. and it's hard to pick your topic and figure out what is feasible and not feasible in just 72 hours.

So my question to all of you is if you think too often me and the other contestants are biting off more than we can chew in that time-frame?

It's a tough format and I would hope the regular BP authors aren't subjected to it... though I imagine they have weekly deadlines, that might be mitigated by being able to choose their own topic/format/style.

That being said, even though the finalists might've bitten off more than they can chew, they did agree to the terms of the contest.

I think the comments about what was left out or should've put in are actually good things.. it shows that people are interested in your topic matter and understood what you were writing enough so that they didn't nitpick on elements within the article itself. In theory, if sabremetrics is a field of research, then it should be a cooperative, collaborative and interactive process and no writer could ever fully encompass a particular subject or its implications in just one article.

As of now, I think everyone has done a great job keeping up.

Everyone is on equal footing. Whether or not 72 hours or 24 hours or 72 days, the equality of the task makes this irrelevant. It'd always be nice to have more time, more data, more assistance, but I still wonder if everyone is using all the resources available.

As for BP writers being subjected to it. I can tell you that we are. Regularly. When Manny Ramirez got busted, you think we could tell our editors that "I need more time to do queries" or that we couldn't turn something around in 24 hours? No and our readers should expect the same.

Will, I think the short answer is "no", people aren't using all the resources available... but I think that might be from a lack of familiarity with what resources are available. Having "Baseball Prospectus Writer" on your resume can probably give access to sources that, as prolific as some of these finalists might have been on other sites, might be harder to obtain with a different background. I imagine some additional sources opened up once BP got their BBWAA card.

Meanwhile, with the exception of one finalist, it doesn't seem like anyone majored in writing or journalism. Finalists have probably been learning their writing skills as they go, perhaps drawing on skills they used to submit work for college or for websites.

I guess I compare it to poetry. I thought I was a good amateur poet and people liked what I wrote. I knew meter and rhyme and all that, but mostly figured things out on my own. Once I took an actual class in an organized setting surrounded by people who had material published, I realized there were a lot of things I didn't know.

Will, it's not so much a fairness, as I realize the what the time constraints are. I guess I'm just pondering if when I'm selecting my topics I'm being too ambitious and trying to cover too much given the constraints. I was just throwing that out ther as a question.

I think it just comes down to how you research a topic, then the framing/editing... I don't think I've read anything by you yet that felt "rushed" or felt you tried to cover too much ground at the expense of quality.

Even with this article, it didn't feel rushed to me...

There might be the odd why-didn't-you-go-there, but I understand it is a fine line to tow. I'd say you, Tim, are overall doing an outstanding job of covering whatever you attempt with the appropriate thoroughness. If you belabour something too small, you become Tim McCarver.

I think BP is at its weakest when it tries to report news. This isn't ESPN. BP had a niche - it did analysis - and I think BP getting away from that has made BP less relevant.

Depends on the definition of relevancy. A few years ago, you only read about them in the mainstream if Neyer posted a link. These days, ESPN and CNN pay (I assume) for BP's articles. If more people read it than they used to, then it is possible that BP is more relevant now than it used to be.

Maybe there isn't as much sabremetric innovation but it might also be harder to maintain a monopoly on sabremetrics. There was a time when you could only get information if you went to a SABR convention. Now, everyone can download a database, run queries, and investigate. So, there are a lot of voices and minds at work, competing to be heard... then consider that sabremetrics isn't as much of a fledgling disciple anymore and the bar is raised.

They're certainly more widely read, now, but they contribute less to the discussion, I think.

Tim I thought your piece was appropriate both in size and scope; I applaud you putting together a thesis with reasonable coherence and value-added graphs in that short time.
I found valid the points raised upfront by Steven G about your explanation/defense of using Win Shares, and by Christina about the margin of error, so to speak, that comes with using that metric to illustrate your case for leaguewide trends. But I thought your main points fit in here just fine, helped by those three interesting graphs

I can't quite put my finger on it, but isn't there an issue with determining overall value provided by positions when the Win Shares framework doesn't properly (and dynamically throughout history) hand out credit between positions?

In the WAR framework, defensive players get credit for their fielding abilities relative to everyone else at their position, plus how difficult their position is to play. The difficulty is determined by how a player with a typical skillset would fare when playing a different position. Sean Smith had a great article about how the relative value of positions has changed throughout history:

Phenomenal subject matter, and good execution. I'm not a big fan of win shares, but they served the purpose of the article very well. As for complaints about it being to much to handle in a sitting: It's not overly math-y, I think about anyone who has ever taken a high school stats class could understand it. And if you have to stop and think about it, all the better. The writing is great, and is more than capable of holding the readers attention if their comprehension lapses. I'd rather read something that is a) fun to read and b) challenges me to understand what's being talked about, rather than having an idea over simplified and spoon fed to me.

I didn't read this article because the title was boring as hell and completely grammatically incorrect. Offensive shortstops are becoming other evolutionary trends in baseball positions? What?

Misplaced modifiers bite everyone now and then. I love them because they are so funny, though. I once tried to write a short story in which everyone speaks in misplaced modifiers and hilarity ensues over the resulting misunderstandings, but it was really tough.

Well, the sub-prime mortgage analog is both unnecessary and inaccurate as contrivances go. And the graphs were both unreadable and superfluous. Take each out and its a really good article. Nice job.
