I can see 12 teams. 4 of those, not Charlotte but adding Phoenix, Phil, Mil, Det, Bos, Atl, Brooklyn, Sacramento.
All could probably use Boozer as he'd be an improvement over what they have or they drafted a project 4, some have cap space to take him, some have few players on their roster to even trade and some don't have much to offer that would be attractive. I don't see any team taking his salary in a back up role.
The Heat and Lakers could use Carlos to fill big holes but they don't have many players to send anywhere in return. Sacramento and Toronto could use him but who could they give up. For most of those teams the players they would be looking to trade would be in the $3-8 million range so they would have to move at least 2 of them to match Boozer's salary.
