Sounds like an ump who is in over his head. I always appreciate a coach who has my back and is on his players when they react improperly.

More than once over the years I've told my players to chill out. The first meeting of the year for the one's that don't know I tell them:

a) I also umpire;
b) I know the rules better than they do;
c) Any discussions with the umpire will be by me only;
d) One call doesn't decide the game if they do what they are supposed to do;
e) Accept the call and move on; and last
f) I will chew their butts out if they even think about arguing a call - I have and I will and they know it.

:D I will honestly say that i have gone out of my way to keep players and coaches in the game. That I have always asked them to stay more than once. I have always remained calm and let them remove themselves. From the way this OP was posted, i think the Ump should be kept down in th ekidie ball.

I think the kiddies deserve better than what you propose. In fact, I think every level deserves better that what you propose.
