In the SI piece, Epstein did say that keeping pitchers healthy was the current "market inefficiency" he was trying to exploit. It's also something both the Rays and Rangers have done alot of work in. You'll notice how slowly both of those franchises bring along their young pitches (except Price, who was an extremely special case/talent), and the Rangers have spouted that pitchers today don't throw enough since Ryan took over. Then you can't help but notice that all three of those teams absolutely love athleticism...If you talk to non-baseball fans the one thing they'll go after after they attack the length of a baseball game is that baseball players are fat and unathletic. Maybe in the steroid era that was true, but now we're going back to guys who can move and move well (and all over the place). I think those teams...particularly the Rays, who've hunted the best athletes they can find since their inception, have jumped on the idea of helping athletes develop into baseball players...the advantages being that better athletes will (hopefully) lead to...well obviously more general upside...but better durability, health, on field versatility, contact ability, hopefully better D...the things you'd expect from someone who is a top notch athlete for their sport. It's probably one of the most interesting things about the sport since the early 2000's statseads vs. scouts debates...Now it's about working together to figure what works best, why, and how to make it happen. It's [expletive] awesome, and it's an aspect I'd like to see whoever the new GM is, Theo or otherwise, make a specific area of study. Absolutely. I'd devote quite a bit of time to the study of movement, mechanics, fatigue, recovery, etc so you can keep your arms as healthy as you possibly can.
