I personally think GSP's wrestling is better than all those previously mentioned fighters, maybe with the exception of Chael Sonnen. Also, the larger weight cut will take a bigger toll on the body of Silva, who could potentially wear down later in the fight because of it. And if anyone can make it a tough, grueling fight it's GSP.
Still, I've gotta go with The Spider in this one. Gonna be strange to see one of them lose but it should definitely be one of the biggest events in UFC and MMA history.
As for UFC 154, great fight. Certainly the most entertaining GSP fight in at least five years. Credit to both fighters for showing heart and grit in this one, and being active.
And Jesus Christ, I don't like Johny Hendricks but at some point you just got to respect him for having that kind of power. Well deserving of a title shot.
