Dallas Mavericks legend Dirk Nowitzki finished his 20-year career with 31,560 points, good for sixth on the all-time scoring list. It goes without saying that he's one of the best scoring big men in the history of the NBA.

Nowitzki appeared on an episode of Ben and Skin and was asked about who he considered his best defender.

The NBA champion didn't give any names, but admitted that it wasn't the taller, heavier defenders, and neither were the much smaller, but quicker defenders. In fact, it was the “medium-sized” guys a la Shawn Marion that were the toughest match-ups for the 7-foot, sweet-shooting German.
