Admittedly, I haven't seen alot of Josh Smith this season, but I think he's going to be a SF.
It's interesting that all of you say he doesn't have the handles to play the wing position. That would be a problem for a SG, but I don't think it's essential for a SF. I've been following Rashard Lewis' career since he came into the NBA, and he couldn't shoot or dribble either. Even now he doesn't really have good handles. But, he's made up for it with great outside shooting and a post up game.
Smith will just have to work hard to improve his outside jumpshot. All reports that i've read say he has great work ethic, so it should be solid within two seasons. With his size and athletic ability, he should also be able to develop a good post game. It's probably going to take some time though, so Atlanta fans will have to be patient.
If you end up with a SF who can give you 15-20 ppg on putbacks, spot up jumpers and the occasional post play, that's gold. To me, that's far more valuable than a wing player with great handles that overdribbles the ball trying to create something while four other guys stand around watching.
