When I think about it, sometimes I want to see that "superfight" happen, sometimes I don't really.
I mean when you watch both guys, Silva is some sort of "natural" genuis, it seems that to him, fighting is like breathing, totally natural.
When you watch GSP, you see more work and intelligence, technique, perfect timing, but he doesn't seem as "natural" as a fighter than Silva and I believe this is why I don't see GSP winning that one, he can't really prepare for someone like Silva and I don't think his "conservative" fighting style is going to get him anywhere against AS.
Maybe he could try to "bore him out" like in the Demian Maia fight, and force AS to do foolish things to capitalize on, but even then, AS is as reactive as it gets. He's able to pull out KO power from virtually any position or move, out of nowhere, he did it on multiple occasions and this is what can beat GSP, if GSP can't plan, GSP can't win and in 4 and a half rounds a drugged Sonnen couldn't beat a wounded Silva.
I really am a fan of GSP but I don't see him standing a chance against AS, the more I think about it, the more I see AS winning this one in, as usual, spectacular fashion out-of-nowhere KO
something along the lines of a flying knee stopping a TD attempt, or maybe reproduce the KOS "jab fight" only with KO within the first 2 rounds once AS gets bored.
But if GSP can come back of a loss against AS, he'll be unstoppable, I see him winning a rematch against AS rather than a first.
