Personally, I think it's more likely Lebron stays in Miami, Bosh goes to Houston and Miami uses their savings to get Melo and Gasol.
What doesn't make sense about Lebron going back to Cleveland is, why did he leave there in the first place?
Because his team was lacking talent and got destroyed in the playoffs by your very own 2010 Boston Celtics. Going to Miami and setting up a Big Three of their own was his only chance to win a ring. But since he seems to be very loyal to his roots, he will give Cleveland's offer a serious thought, also in part because of Cleveland's present and future talent situation. I think Cleveland is going to be a big player in the East again for years to come if they get LeBron back.
But if he goes to Cleveland, who is the new "big 3" going to consist of?
Lebron, Kyrie and Wiggins?
Is that really a big 3?
I am sure Cleveland will try pursuing other avenues to add more talent, but who's to say they will end up being successful?
And who ends up playing center for the Cavs?
I've always felt that Lebron should go to Houston.
I think him, Howard, Harden, Parsons and either Beverly or another halfway decent guard like Mo Williams would be unstoppable.
