Pitching mechanics have become a hot topic of late. I often (but not always) talk about a pitcher's delivery in my Top 11 Prospects series, but it has really gone one step further, with any number of people and websites breaking things down, often in a way that is, frankly, just wrong. I'm not saying they're all bad, but I've also seen some laughably bad analysis out there. I've tried to discuss it in chats a few times, but for whatever reason, it finally crystalized for me during an e-mail interview with the folks at Phuture Phillies, which can be read in its entirety here.

phuturephillies: Phillippe Aumont seems like one of the more polarizing prospects among Phillies fans right now. On the plus side, you have the big arm strength and great sinker, which will play well in Citizens Bank Park, but on the downside, I’ve seen some criticisms of his mechanics, and he does throw across his body. How much should we worry about him breaking down, and will it be better for his arm to potentially be pitching three days in a row, or once every five days? With his fastball being as good as it is, can he be a mid-rotation starter even if his curveball and changeup are just average big-league pitches?

Kevin Goldstein: I’m not saying his mechanics are perfect, but unless you are talking to a scout or listening to a pitching coach, I wouldn’t worry too much about what people say about a pitcher’s mechanics. Again, I have no idea where these criticisms you mention are coming from, so I might be totally barking up the wrong tree, but there’s a lot of people out there masquerading as some kind of mechanics expert, and it’s all quite silly. Does he throw across his body? Absolutely. Is he off-balance on landing? Absolutely. Will he get hurt? Maybe. But that’s the life of the pitcher. You a big Felix Hernandez fan? You think he’s good? I sure do, but those are hardly pretty mechanics either, but what can you do? You start messing with it, and you don’t have Felix Hernandez anymore. Pitchers get hurt—a lot. Like a crazy amount. It’s part of the game, and it’s just something we might be better off accepting. Watching grainy YouTube videos in an attempt to figure out who and when is a fool’s errand. Ok, now that I’m done ranting, back to Aumont. I think he could definitely be a mid-rotation guy, but I also think he can be much more if some things work out. The fastball really is a special pitch. I’ve seen the guy in person on multiple occasions, and it’s very, very hard to find that kind of velo/movement combination in a fastball, and he will flash a plus breaker. There’s a lot of upside here, it just comes with some risk. How many high-upside prospects don’t come with a lot of risk? You don’t need more than one hand to count them. Man, I went on way too long there.

One guy that comes to mind when the online experts begin knocking pitchers due to mechanics is Chris Carpenter.

The online experts say he has bad mechanics and with his medical history that really can't be disputed. My only response is, so what?

If any prospect ends up having a Carp type career, injuries and all, I think you have to say you hit the jackpot. Like you said, that's the life of a pitcher.
Prior's mechanics were flawless. He had the "ideal pitcher's frame".

What did all that get him?

(Dusty'd i guess)
This seems overly dismissive to me. Just because getting hurt is common for pitchers doesn't mean a pitcher's mechanics aren't important or that we shouldn't try to fix things where appropriate. And in fact, you acknowledge as much in that you mention mechanics more often than not in your prospect rankings. If your point is that there is some bad analysis of mechanics out there, point out the bad analysis. Is that your point? I don't really get it...
