First tossed coach of the season!

[WhistlesAndStripes]

If you really want to keep this coach in the game(personally, I wouldn't), you just issue a single bench technical for the actions of the ASSistants. You can say that one of them said something that was over the line, you're just not sure which one, and that still puts them all on warning.

I have also been taught that once you T a coach, you get out of there and let one of your partners take the position in front of the bench. In a 3 man crew, we generally have the calling official go far side to administer the throw in. That way, if the coach is giving someone an earful right then that requires a second T, it's a DIFFERENT official that makes the call. And if it's the same official calling the T, it's pretty likely that everyone in the gym knows why he got it.
