After seven seasons with the Cleveland Cavaliers, whom he dragged to the 2007 NBA Finals despite a ragtag supporting cast, James opted for sunnier skies and teamed up with Dwyane Wade and Chris Bosh on a Heat superteam constructed by Pat Riley.

Being above that second apron, the Cavaliers' ability to trade future first-round picks is frozen, they can't aggregate contracts within a trade, and are unable to include cash in any deal, either. So, for a seismic trade involving a name like LeBron, the route to Cleveland having the means to get a deal hashed out looks to be a tough one.
