Rampage has stated that after this fight with Glover, he's done. Silva is only a shell of his former self, but he still has some power in those kicks/knees/punches.
I'd like to think the most competitive fight would be Vitor/Sonnen. Chael would have to be careful on the ground as Belfort is no slouch in JJ.
Imagine this scenario: Freak upset, Sonnen wins LHW belt. Then, he grants Vitor the shot and loses.
We have Belfort vs. Jones II. Ahhh a guy can wish.......
