I posted this in another thread the other day and davell mentioned a similar thing earlier too: I heard an interesting interview with Tommy John the other day. He theorizes that there's more pitcher injuries now because these kids don't get the down time to let their arms recover in the off season because they're essentially playing year round. I hadn't heard that particular theory before and coming from a running background, it completely makes sense. I've seen a ton of runners ramp back up too quickly after a marathon and end up injured when if they had taken a month or two and just done some low, easy mileage they more than likely would have avoided any issues. With all the fall ball and summer leagues, these guys just don't get enough of a break
