I don't think the Heat are worried about the Magic at all. Sure Howard can go off and score like crazy since he outmatches the Heat interior, but the Heat have one of the best perimeter defenses in the NBA, if not the best with Battier on the floor, and Orlando absolutely lives and dies by the outside shot. They have never, ever, ever been a team that dumps it down to Howard and lets him go to work because that strategy works for a quarter then everyone plays Hack a Dwight and Orlando finishes the night with 59 points. Orlando will go exactly as far as Anderson carries them. He is their best perimeter threat by a mile. If he is off or being shut down by Battier or LeBron, good night Orlando. Orlando beat the Heat the other day thanks to their big emotional boost from Howard's decision and Nelson having his best game in a long, long time. And even with that, they barely beat the Heat. In a seven game series with the new addition of Turiaf off the bench, the Heat will destroy the Magic and thats assuming that the Magic get past Atlanta or Indiana or whoever they play in the first round which I wouldn't bet a dollar on.
The only team I would pick Orlando to beat out of all their potential matchups (NY, Boston, Indy, Atlanta, Philly) would be Boston because they have absolutely no interior players at all. The Heat don't have the best interior guys, but they at least have guys that are decent and LeBron one of the top two most versatile defenders in the NBA. Boston literally has no big interior presence except for an aging Garnett. Philly has Iggy,t the other most versatile defender in the NBA, Hawes, Brand, Vucevic, and Young. New york has Chandler. Indiana has a plethora of guys including Psycho T who may just go out and hard foul him six times and completely throw off Howard's game.
