Smart is not an intelligent player - never has been. In fact, he is down-right dumb and a dumb veteran at that. Doesn't learn from mistakes.
He consistently takes bad shots, he is sloppy with the ball, he is either great or awful down the stretch of close games, he does not run the offense. I always thought he was the type player you needed to win a title - that intangible, big play hustle guy. Can you imagine how bad Marcus Smart would be in a tough, series-defining Game 4 in the Finals ?
