What's the Point?

Coach, while I can't say whether or not I'd have made the call (I probably wouldn't have even noticed him since I pay far too little attention to coaches), I will say that the official was correct by rule. It's tough to question the call made by an official when a) he was right by rule; and b) we weren't there to see the rest of the game (context).
Obviously, the suggestion would be to make sure your assistants know the rule and to keep a tight reign on your bench.
