GSP by submission. I love both of these guys so it's going to be a tough one to root for, but I see GSP's experience and freakish ability getting the better of the Pitbull.
I agree. GSP has the experience, but Alves is a tough dude. GSP is strong, and so is Alves. That part of the game is going to neutralize the fighters. It will be a standup fight with GSP getting the better of the exchanges - especially in the later rounds.
