I know what you are saying and I agree with you in principle. The game should be called the same way from the first tip to the final horn. Although every good sports official will also tell you that you need to read the game -- what maybe wasn't a foul in the first minute or so becomes one in the 14th minute if play is heating up, if play is getting chippy, if you need to introduce a break into the play to allow the players to cool off and drop the emotional temperature a bit.
As far as making the critical call on the last drive or at the last second, it becomes increasingly unlikely that's going to happen. Most officials will feel their blow of the whistle should not be the potentially deciding factor. While some might agree that Valentine may or may not have stuck his hand through the net on Mel's tip-in at the end of regulation in the MSU game, can you imagine the ****-fest if that had been called? It's just the reality of the way sports contests are called. And has already been mentioned, there may be some guidance from the NCAA referee's committee and/or the leagues to call only the most egregious of fouls at the whistle. Seriously.
There would have been no complaining had the call been made. It was a blatant violation of the rules. It wasn't a judgement call or a 50/50 call.
