In the context of a typical NBA game, I'd completely agree with you. In the context of this particular game, one of the most poorly called games I can remember seeing, ever, it's more than a little disingenuous for the NBA to single out and recognize one single bad call out of the gaddam cornucopia of officiating failures that went on over 53 minutes.
I don't blame Houston fans for being frustrated with the officiating -- any fan of the game, partial or not, was likely disgusted by the refs that game. But c'mon. A petition to replay the last 10 seconds? Might as well go back the start of overtime. Or the 4th quarter. Or hell, let's just replay the whole damn thing. As much as I'd hate to lose the W, at least that might actually restore some credibility to the league's officiating. Calling the foul on Dwight the single most significant officiating failure is just statistically false, and does nothing to help the public perception of NBA fairness.
