I can still remember the day that Gary Huckabay and I met up in Coronado to talk about the future of Baseball Prospectus, though I don't remember the exact date. There was a lot of tension on the team and not a lot of money to go around, and our default position was just blowing the whole thing up and saying our goodbyes. We ended up selling each other on making a go of a greatly expanded content offering, though, most of which would be available (*gasp*) to subscribers only. We both expected paying for content to be a tough sell to prospective subscribers, so after laying out the content schedule for the long-time contributors already on staff, we looked it over, and it looked qualitatively strong but a little thin.

"Now what?"

"Well … who's this Under The Knife guy I've been hearing so much about lately?"

It seems like forever ago when we were first introduced to Will's legendary energy, immense enthusiasm, expansive knowledge of human physiology, and formidable network of sources. Will has informed and entertained for over one thousand of his signature Under The Knife columns, he created the very popular (to readers and other sites alike) "traffic light" injury risk rating for his annual Team Health Reports, and he's worn many different hats at Baseball Prospectus behind the scenes in his copious free time.  But Will has decided that it's time for him to move on, and his column today will be his last at Baseball Prospectus.  Whatever he ends up doing next won't be a secret–@injuryexpert has been known to test Twitter's limits–but one thing's for sure: many people inside the game and out will be watching.  Powered by best wishes: thanks for the volume of memories, Will, and may you be happy in your travels.

Under The Knife was one of the more popular columns at Baseball Prospectus, and we were planning to provide it to subscribers for quite a while. Luckily, we've got some very interesting quantitative injury analysis to present on Thursday as part of Reintroducing PECOTA week, and we plan to continue providing cutting-edge injury analysis in 2011.

And if you're an excellent, experienced baseball writer with a following who has proven to be a reliable multiple-times-a-week contributor and wants to work at an outfit that doesn't do TPS reports, we are looking to make your acquaintance.
