Marcus Smart is back, and he looks lighter and leaner to me. It appears that he may have spent his injury down-time wisely. His best move last night against the Chicago Bulls was not a play and was not even part of the game. But it got everyone's attention.
Needless to say, the ninja kip-up is not an easy maneuver. Being lean, strong and athletic certainly helps. Visually, Marcus looks to be the leanest he has been since joining the Celtics, and he has always been one of the strongest guys in the NBA.
