I wrote something about pitch counts, particularly as they relate to Stephen Strasburg. Are links not showing up for you? They just look like normal text? I have complained about that.
I was thinking about this, in an ill-formed kind of way: is there an analogue in any other sport to pitchers' arm injuries? Is there a body part that routinely fails just as a result of an athlete doing his job? I guess soccer players have a lot of leg problems, but that seems to be from people regularly diving cleat-first into them. Plus they're faking half the time.
I don't know. Concussions in boxing, maybe? That's from getting hit, but that's half the job description. Do beach volleyball players get really bad sunburns? Do mixed martial artists start getting a little too used to having a sweaty man in combat panties on top of them? I don't know. Just thinking out loud here.
