Absolutely true. If the Spurs had played with any sort of drive and passion and done the little things that are necessary to win, the call would have been irrelevant.
While I do think there will be some major officiating issue in the coming playoffs, I still don't subscribe to the notion that officials turn games, in general. Great teams play through bad calls, get stops, and find ways to score. If you can't do those things, you don't deserve to win, no matter how egregious the officiating might be.
