Orlando - This team has an identity crisis. They don't really have a starting center or SF. Instead they will plug holes with All-Star caliber players(Amare and JJ) playing out of position and hope it doesn't show. Long term it will.
I think you're underrating the Magic, here. I'll give you that the Cavs and Magic are a potential toss-up and you're heavily biased on that one, so I'll let it go

but we are better than the Bulls. Outside of Rose, there's nobody that scares you on that team.
I also don't think I have players playing out of position or have an identity crisis. I have length and defensive talent in the backcourt with Holiday, Brewer and Johnson. JJ has played most of his career as a SG but at 6'7 240, he's going to be a SF for the rest of his career sooner rather than later. I don't think he'll have too much trouble adjusting, and the 6'7 227 defensive stopper Brewer can handle almost any 3 if there's a guy Johnson is having trouble with.
At the bigs, Kurt Thomas is going to give you 15-20 minutes a game of limiting opposing centers to a 13 PER, solid rebounding and grading out well in Synergy as the 19th best post-up defense man in the game. Vucevic can also give you 20 minutes of the same with more size, and both can space the floor with a crafty jumper.
With Thomas and Vucevic taking up ~31 minutes, Anderson with 31 and Amar'e with 34, that leaves 2/3 the game with a real center on the court and 1/3 of the game with the Anderson-Amar'e small-ball combo, which isn't even that small. Amar'e is 6'11 260 and guards centers actually better than power forwards, statistically, and that's a defensive nightmare to guard. The Celtics and Heat both went very far, and the former won, giving big minutes to small-ball lineups. I'm just looking to close out halfs with that lineup, like the Celts did with Posey.
Consider that the Magic win 113-101 per 48 with Anderson on the floor and lose 92-104 with him off it, and the numbers are much closer for Dwight, and you can see that his presence is invaluable even when his "center" is Big Baby. If the Magic can play with Baby and Anderson and succeed as their frontcourt, then by golly we can succeed with Anderson in Amar'e.
This team has offensive firepower all around with Holiday, Mayo, Johnson, Anderson, Amar'e (good luck guarding that lineup) but still great defense with Jrue, Brewer, Johnson, Thomas. What you're calling an identity crisis is what I call balance, consistency and flexibility.
