With Bosh set to join Wade in Miami instead of doing the sign-and-trade and joining LeBron in Cleveland, I have no idea how LeBron stays in town. That doesn't mean he won't, and it doesn't mean he wouldn't have competitive reasons to, it's just that those reasons are not readily apparent. Their roster is what it is, and they don't have much (if any?) cap room. It comes down to whether or not they're able to work trades is and obtain the right pieces.
Then again, Shaq comes off the books this year, right? Does that give them any room or were they screwed without that salary anyway?
