The Line

[BktBallRef]

It's really difficult to address all of the possibilities but here are a few basic guidelines.

I allow a coach to...

...complain about a call or no call.
...ask a question about a call or no call.
...address me in a manner in which he would like to be addressed.

I don't allow a coach to...

...question my or my partners' intergrity.
...become personal, or yell at me.
...use profanity or vulgarity.
