J.R. Smith is normally the guy watching Carmelo Anthony hit the game-winning shot, not the one knocking it down. But with Anthony nursing a lacerated finger, the New York Knicks turned to Smith for the last shot, and the eight-year NBA veteran delivered. Smith hit a fallaway jumper from the left wing as time expired to give the Knicks a 100-98 victory over the Charlotte Bobcats on Wednesday night.
