Definition of an Umpire

[DG]

There is a difference between a coach who knows where the line is and one who doesn't. The first is more likely to walk up to the line and not cross it, the second has not a clue so he doesn't even know when he crossed the line so toss him quick and get on with the game. If a coach who knows where the line is (and an experienced umpire will know who this is) crosses it's because he is either 1) doing it on purpose or 2) out of control.

My last ejection was a college pitcher, who after a call I made on the bases screamed at me "you are f*ck*ng kidding". Heck, I could have blown the call, although I don't think so, but he clearly did not know the line. When the manager came out to ask what happened I told him and he asked me how much time he had to warmup the next pitcher. I said "as much as he needs". The manager knew the line. He didn't say a word about the call.

Most sub-varsity coaches don't know where the line is.
