This was nice footwork. It is very hard to stop Harden's 3pt shooting. He has good size, first of all. But also they can't get too close or they'll foul (either by blocking a drive or by undercutting him after the shot)
Its called the Zoolander since on that play he can't turn right. Don't you guys get MDA gazette weekly? DM Morey on twitter and he'll hook you up with a free trial.
I saw Klay Thompson doing that shot in drills before he was drafted. I thought to myself, who would ever take that shot in game? There you have it, James Harden. Making it look easy.
