Here we have J.R. Smith turning Cavs rookie Anthony Bennett from player to spectator. First, he blows by Bennett with a pretty gnarly crossover and then continues on to the rim where he finishes it off with a windmill dunk. Clean, quick and decisive. All in all, it's a pretty nifty little bit of hustle-bustle.

Here's a GIF, because it's fun. The little hop flourish at the end is great.
