Coaching box

[JWC]

Boys Freshmen game last night. B's coach is getting on my partner for a call. We go up and down the court a few times B is getting drumed. B's coach will not get off my partner. Finally my partner tells the coach he has heard enough. Coach keeps going with his mouth. Partner says he has heard enough sit down. Well coach response is you cann't tell me to sit down! Partner T him up.

My question is can you make a coach sit in this situation with out giving him a T? All I have found in the rules is he has to sit if you wack him with a T.
