at 6'0 I don't see how he is going to raise his stock any by playing another year, he is what he is. Smith just won a national title and there is no way they get to the finals without his tremendous play throughout the tournament (outside of the championship obviously).
I mean, I go to UofL, I am not a fan, but have watched Russ play enough to know he has world class speed with a ball in his hands and gets to the cup at will. He racks up an insane amount of steals as well. Now I don't think the guy has a bright future because of his size, but I think he would be a lottery pick at 6'5.
