So, you mean one option? No way he goes back to Cleveland. I know they have cap room, but that's because they are terrible and have no one to play opposite LeBron. Besides, who would want to go back to play for that owner after the **** he talked about him when he left?
Kyrie Irving and Luol Deng are a good and decent piece. Not sure how good Spencer Hawes is but his points per game look decent. Then I guess you hope Anthony Bennett develops. Not the most desirable team, but certainly good enough, if combined with some title chasing veterans, to compete for a championship. But I agree that the biggest issue is that Lebron pretty much said he didn't care for Cleveland when he picked Miami the first time. Basically said just because he was from Akron didn't mean he liked Cleveland and that they actually disliked people from Cleveland growing up.
Also, if he wants to compete for championships, it will be a lot easier to convince over the hill veterans to sign for the veteran minimum if he is in a place like Miami as opposed to Cleveland.
