Another thing to consider is that many of the current players and many players in our youth programs are concentrating on one sport instead of playing multiple sports. Each sport uses different parts of the body. As a reminder, I believe Mauer played 4 sports and had a full ride scholarship to Florida State and Bobby Bowden to be his QB before being drafted by the Twins. I'm sure we all agree Mauer made the right choice. My point is that the different parts of the body that were really taxing on Mauer playing baseball weren't used as heavily in the other sports he participated in while he was still able to stay in game shape by his other sport participation. I see the effects of this even as low as HS sports in very rural communities. Even in these rural communities, many HS students have access to travel teams, sports therapy programs, camps, etc. so these muscles, ligaments, joints, etc. are never truly rested to the point they can recover, and IMO leads to injuries at a higher rate and continue to get younger.
