True, he is not as aggressive every night at driving the paint. But the thought is that Harden NEEDS the refs to score in the paint (many people think this.) when the truth is Harden is one of the best finishers in the game. So if the defense is not stopping him from driving then he easily gets two points. The fouling is just a bonus because some nights when he's this aggressive at driving the only way to stop him is to foul and just hope the refs don't call it.
What was the point of even doing that. He just spun Harden around and thought that wasn't going to be a flagrant?
