The Heat should not have any chemistry issues at this point in the season. What's going to hurt them is the lack of a true defensive big man. They could hit a wall against the Magic or the Bulls. I'm going to stick with the Bulls because they are the most complete team. They are tops in almost every significant defensive statistical category and are one of the best rebounding teams in the league. Rose has molded himself into a legit first option, Boozer gives them a reliable post presence, and Deng can score from almost anywhere on the floor. On top of all that, I really like the Bulls bench, they have smart guys who play within their roles. A team who takes pride in playing defense will always get far.
