He should definitely leave and stay in the East. He could have a team that may be slightly lesser than San Antonio and still win a championship because his road to the finals might be much easier.
I'm still rooting for Cleveland. Irving, a #1 pick, and room to sign one more guy? maybe his ol' buddy melo? One thing about this Heat team was it felt like when they needed a scorer and Lebron wasn't in it, there was no one. Dwade used to be that guy, he isn't anymore. Melo I think still can be.
Wherever he goes I hope he brings Jesus Shuttlesworth with him. I saw he still has some game and I think he is cheap.
(I was thinking today when watching him congratulate the spurs, it looked like he whispered something in Danny Green's ear...maybe he wants him too)
