I see the K-Mart comparison, at least visually. Also reminds me Korver in the way he moves.
He'll have to show he can actually shoot at the NBA level, though. As Koz notes, he didn't show he could consistently shoot at the college level, though he was facing a lot of defensive pressure.
Just being a fantastic shooter is no clear indication of being a really good player, though. Anthony Morrow is one of the best shooters in the league and he's had a hard time nailing down a rotation spot.
