Yes, bench decorum is a point of emphasis this year. Given the fact you mentioned this was a D1 game with at least one great official, you can see some of the problems involved with enforcement. I know as I work a game, especially like one as you mentioned, "the action was fast and furious on the floor with a lot of contact and potential for it to get out of hand", I would find it hard to be watching the bench. That said, we are also taught to be aware of those items, just as you are aware of your partners' locations, game clock, shot clock, etc. We may not be focusing on them, but we should still be aware. But, then again, how are we supposed to be aware of players standing when the action is at the other end of the court?
If there were actual issues with the bench that were not taken care of, you can be sure the crew will receive a call from the supervisor. However, not having been there myself, is there a chance that the players were reacting to a play of some kind? Or, maybe several plays? This could be one of those "gray areas" where if the coach and bench aren't attracting attention to themselves, the officials aren't going looking for trouble.
Obviously you noticed because it affected your view of the game. Maybe, if you moved to a different seat, you wouldn't notice it as much either?
