I don't talk to assistant coaches. I'm not rude about it but direct. I have great relationships with coaches and assistants - even some that joke wth me about not talking to them. If they come out and insist on talking - then I'm a little more rude and sometimes downright obnoxious. I have a buddy that I work with a great deal who is worse about it than I am - and we were working a game where the assistant was one of his buddies. One time down the floor, he leaned down and made a comment to his buddy who said - "Sorry, I can't talk to you - my buddy's a prick about letting us lowlife assistants talk to refs!"
