Marcus Smart is in his fifth year in the League, and he has never been on the NBA All-Defensive Team. That needs to change. Yes, I get it. Analysts still don't know how to define Marcus, and neither do I. But one thing is certain. He is a tough-as-nails defender that opponents hate to face.
Smart ranks eighth in the NBA in steals with 1.8 SPG, but that is only one traditional stat. I am going with Defensive Real Plus Minus (DRPM) on this one.
