I go back and forth over Orlando and Atlanta as the #2 team in the division. I think the reason that I give the edge to Orlando is because Atlanta is relying on two big men who aren't healthy. Joel P. isn't himself this year, and Haslem is inactive.
I'm not sure about Orlando, though. Felton is a good fit at PG, but I worry about DeRozan and Beasley on the wings. These are two guys out to "get theirs", and when Beasley was playing on a winning team, he wilted and showed he wasn't ready for primetime (which is why Minnesota landed him for a 2nd rounder). I wouldn't stake my playoff fortunes on him. Also, I'm just not a huge fan of Channing Frye, although his skill set definitely fits well next to Howard.
I guess my verdict would be that Orlando would be likely to win this season, based upon Atlanta's injuries. Next season, though, I'd give the edge to the Hawks.
Nobody in that division -- or in the East, for that matter -- is beating the Heat, though. Not that that's a slight against any of the other GMs; Miami just had such a built-in advantage. (Meanwhile, I feel for Orlando; they have a good record, but not a great second keeper player. Dwight is great to build around, but Orlando was handcuffed by not having a great running mate to pair with him. In that regard, Beasley is better than anything that was on Orlando's roster, most likely.)
