J.R. Smith of the Knicks may have lost a step or two over the years, but his dunk on Ian Mahinmi on Thursday night against the Pacers was absolutely ferocious. J.R. Smith cut down the lane and poor Mahinmi made the mistake of trying to get in his way, he was unfortunately awarded a life-sized poster. Smith was also fouled on the play, insult to injury for Mahinmi.

Though it may not have been a highlight, Smith also made Twitter shake a bit when he tossed Lance Stephenson to the ground during the same game.
