There are some good points made.
I don't think of him as a poor man's Gay. I think of him more as a poor man's Josh Smith. (just for comparison)
I'm also not sure what he brings to the team, but he's got some good qualities. Great athleticism, pretty efficient scorer (even without a 3 pter, which isn't so bad if you use him at PF, because he doesn't take the "pull your hair out" 3s that a Josh Smith might), pretty good defensive player. Nothing special though in any way.
