In Mississippi, we have a meeting with the game administrator and coaches before the meeting with the captains. At the first meeting we give them cards with our names on it so they can rate (BS) us after the game. In this state, I don't see how they could get out of this. It would be so obvious that they are acting like jerks when everyone is waiting on them.
There is really no way I think a coach walking away should be a T. However, that coach has clearly showed the he/she doesn't want to communicate during that game. A time will come during the contest where the coach will want to talk. Handle this accordingly.
