Clippers are a failed project. They'll never reach the conference finals the way they are. CP3 is getting older and he's hungry for a ring. Could CP3 pull a 2010 LeBron and leave for Cleveland to unite with his best buddy? It's CP3's only realistic chance at a ring.
Obviously, there's a such thing called a salary cap, but I'd be willing to bet that the Cavs could move some pieces around to make it happen.
