Take it as you want. The umpire is not there to put on a rules clinic. If they want one, go to one. I think I am going to start taking Tim_C's attitude on these things and say "Go hug a tree".
The coach is there to teach him. The umpire is there to call the game. If something happens that the coach doesn't understand, then he is the one to talk to the umpire and get a clear understanding. If he doesn't have a problem with it, then his players don't have a problem with it.
Pretty simple philosophy isn't it? Coach teaches, umpire calls. What about that doesn't the batter get? If he has a question, ask his coach and his coach can ask the umpire if he can't explain it himself. Nothing arrogant about that.
