How much crap do you take?

[ajmc]

I am in no way suggesting that anyone go looking for trouble, and I understand coaching can be a very frustrating experience, but if, "the coaches were competing with each other as to how many F-bombs they could say or shout.", you need to call their attention to the simple fact they are behaving badly and advise them to stop.

First, because you don't want them to make complete fools out of themselves and alerting them to how bad they are sounding is an act of professional curtesy, and second (if need be) they are violating
NF 9.8.1.a, "Using profanity, insulting or vulgar language or gestures." (Note there is no mention as to whom the objectionable language is directed to).
