Harden actually rarely swishes the net. A lot of his shots hit the back of the rim and go in just like that. Personally, I don't care, as long he's making them haha.

That would have been great as well, PJ Tucker just about fell completely over. I don't think Harden put on as many dribble moves during that possession though as the time was running out
