What about this?

coach is a moron....I like the idea of going by watch you see out of the pitchers body language and if he is losing his stuff but at some point common sense has to come into play.

Not all of these guys getting Tommy John surgery have played Select ball or year round ball have they? They should do some research on what pitches these guys are throwing, any new pitches they are trying, etc. Have there been any recent changes to the baseball?
