From what I understand the Heat aren't done yet. Ira Winderman wrote that the Heat are still looking to sign Rashaard Lewis and Marcus Camby. Lewis as a minimum contract and Camby in a possible sign and trade for Joel Anthony. If this indeed happens, wow is all I can say.
So from my understanding if all of this happens the 2012-2013 Heat roster could be:
Pg Elmario Chalmers/ Norris Cole
Sg D-Wade/Ray Allen/ Mike Miller
Sf LBJ/ Shane Battier/James Jones
Pf CB1/ UD/ Lewis
C Marcus Camby/ Dexter Pittman
Happy Lebronukkuh indeed
