I think I did kind of do it that way. I can't remember my exact phrase but it was along the lines of if you want to discuss it then you need to come here instead of yelling from there.
This coach had problems last year I found out later where he had been ejected. I question why he is still allowed around the children. It is pretty obvious he is in it for his own glory and no the kids.
Most coaches know me as a very reasonable guy. I have no problem explaining any rule that they disagree on if they go about it the right way.
Thanks for the responses guys, I like hearing better ways to handle a situation!
