I'm starting to wonder if all the Shields praise from GSP isn't a part of his strategy, maybe to get Shields overconfident or something.
Silva is from another planet, plain and simple, he seems to fight as naturally as we breathe, I have yet to see him gas out.
GSP for a win, maybe
Shields for a win vs silva, maybe there's too much of a gap in experience here.
GSP and Silva both spent their last years to fight top contender after top contender, they're now "used to" fight tough, long and difficult fights, they both have the cardio, they both have the talent, the chin, the condition and the work ethic. And more important, none of em ever rest, they both keep working hard with top trainers and coaches, in many disciplines.
At this level, let it be GSP or Silva, they're like the beatles or jimmy hendrix of MMA, true artists, they're not even "fighters" anymore.
That being said, I see silva a little more "solid" and "mature" than GSP (who's also caught in the "I will not fight friends" BS)
I see silva retiring should he lose his belt
