anderson silva purposely didnt finish thales because he wanted to show his good conditoning. Everyone said that gsp's conditioning would have been the deciding factor if the two were evr to fight. Not anymore. Gsp may still be in better shape, but not light years ahead of anderson like he was thought to have been before.
And Machida, I like his style and elusiveness, but i just dont like the guy. i cant explain it. but that has nothing to do with anything.
Anyways what im trying to say is Silva will beat GSP when they fight.
