Sad to say that i think Silva wins because he is bigger and he hasn't been laid out for the last year. I am a big GSP fan but i honestly think if he doesn't pick some cream puff to fight when he first comes back he will probably lose his belt. To be off as long as he has over an injury will take a fight or 2 to get his mojo back, only so much can get back in the gym, you need the timing and stuff from a real fight
