I also worry about a few things in this sort of scenario
01-- shutting down can put the player in a position of not being in "tip-top" shape when he wants to be ie--at the camps
02-- you run the risk of pitching when not in tip top shape therefore hurting your chances and also running the risk of injury.
03-- the mental aspect--the player may not be as sharp mentally as he would without a shut down
Just a few thoughts from one who has been there
