Yeah, it had to be on Garnett and any given post play they can call it as someone is always camped out. I am not the biggest fan of the refs and I do believe they heartily pad LeBron James stats with FTAs. I mean they have sunk millions of marketing into this kid. He is an investment. The Lakers were in the post much longer than that and they were not called in the finals. So 3 seconds is always a selective call, they call it when they want too and don't when they do not.
NBA refs blow more calls than anyone. But its because of the instant replay and we see how they were faked out by the players. That being said, they still do a bad job most of the time. No other sport, not even football has as many star calls. Baseball and football refs are often reinforced by the instant replay, not all the time but a lot of the time, NBA refs are not.
