I'll try to find a link later, but if you aren't watching the game, check out the flagrant 2 called on him blasting Harrison Barnes on a screen. Cavs were down over 30 at the time. He wanted to hit the shower.
Its a good thing Steph saw his guy falling into him last second. Had he kept his right foot planted in the position it was just before getting hit, that could have done some real damage to his knee.
