Bill Simmons just mentioned on his podcast that he think that Smart leads the league in taking a bad shot and immediately attempting, and often succeeding, at forcing a steal on the other end. It's anecdotal evidence but I think I've noticed the same thing.
You imagine what he could do when he's 3-4 years into the league after he begins to understand all of the player tendencies and further develops physically. The amount of bad shots should decrease while the defense improves.
