I'll throw out a name that hasn't been said:
Houston.
That's if he's really about winning shyt like he's saying. If he just wants to moderately compete and get paid for nothing then he can go to LA & Chicago, he just won't ever win anything. He'll barely make it into the playoffs in LA and he'll be behind MIA/IND until he retires in Chicago. Melo to Miami wont happen.
So it's kinda self explanatory why Houston, Harden/Howard together is better than Kobe by himself at this point or a busted up Rose. And with the way Houston is set up, they could make a Melo signing happen or at the very least trade with the Knicks. Everybody on Houston's cap other than Howard, Harden, Asik, and Lin make less than $2 million. If it just came down to it Houston could move Asik for a straight cash dump and I don't think they'd have much problems moving Lin if they had to, then sign Melo and still have room to improve the bench. The stars seem aligned for one of Melo or Love to end up in Houston, that is if they aren't trying to go to LA.
Looking at Houston's salary book makes me realize how much of a steal Parsons is though, he's only going to make 967k next season.
