I've never understood the Wade comp. Just because they're aggressive SGs with poor jumpshots? But Wade is on another plane from Smart as an athlete and ballhandler.
If I was going to compare Smart to somebody, it would be a slightly less athletic Tony Allen. Competitive as hell, takes pride in defense and can guard multiple positions, probably don't want either of them creating offense too often at the NBA level. Smart probably shoots a bit better than TA, so there's that.
Useful player, no doubt. Pretty high floor. But the Wade comp implies that this kid should turn into a star, and I just don't see that upside unless he's allowed to stat-stuff on a bad team a la Sactown Tyreke.
