This is an interesting idea for CME or CPD or whatever they call it nowadays. Why not spring training every year for everybody. Go over some new things in medicine, practise up on skills that are rusty.
The idea of coaching is interesting too. When a player is having trouble at the plate, he asks a coach (an ex-player) for help or the coach approaches him. Why don't we have a similar model in medicine?
Eventually some academic will have this idea which he will promote as if it is a new concept even though baseball has been doing it for a century now.
