Now this is all on the offensive side of the ball. It's no secret that Wade and James are willing to put the work into playing defense, and they are very good at it. So while they wont have the great inside defender, I don't think it will matter since the league is really turning into a outside oriented game.
True that most teams offenses are outside oriented, but all the best teams have huge threats inside. So while there is no doubt this Heat squad will breeze through the regular season, its going to be interesting during the playoffs. Look at the four teams who made the semi-finals last season - Lakers, Phoenix, Celtics, and Magic. All of these teams can play inside, but more importantly they can defend inside. Obviously the Heat will be a driving team on offense, but will they be able to defend Pau and Bynum, or Howard?
