I have a really hard time throwing a name like Gary Payton or Joe Dumars out there because Smarts offensive game isnt in their class yet. If we're talking just defensively and leaving position out of it, I think his defense compares well to Artests
If we're talking total game on both ends of the floor, where Smart stands right now, the best name I can think of, and Im probably gonna get killed for this, is Lindsey Hunter.
