This summer of free agency has been pretty hectic, complete with surprise sign-and-trades and plenty of movement around the league. As more "superteams" pop up around the NBA, the Miami Heat's chances of winning back-to-back titles depreciates.
From Steve Nash's move to Los Angeles to Deron William's decision to stay in Brooklyn, this has definitely been an exciting offseason. The Heat have made some moves of their own, including the acquisition of Ray Allen and Rashard Lewis.
The winners of the 2012 NBA Championship will definitely come back strong next year to defend their title, but these eight teams will give them a run for their money.
