Good comparison except I think Barnes has a better head on his shoulders. Barnes will be a productive outside shooter for somebody in the NBA. I think he will be a better scorer than Marvin Williams. Based on his sophomore year, it's clear Barnes is a role-player and not a star in the NBA. He won't be able to create his own shot and will need a good PG to feed him the ball. OP, "extremely athletic and strong" by NBA standards? Ain't no way. And the comparisons from a couple of years ago are nowhere to be found now. The shine has dimmed off this guy. Before last season started, he was touted as the obvious #1 pick by many prognosticators but looks like top 5 is a reach.
is it just me or does he looks like Kwame Brown? I haven't followed his NCAA career but I remember a few years back I was very impressed by him at the Nike Hoop Summit.
