Sonnen is a bigger, stronger, and better wrestler than GSP. There is no way GSP could take the punishment Andy inflicted on Sonnen either every time Silva hit him his entire body contorted. Silva has knocked out two former UFC LHW champions with a back peddling jab and a front kick. It is seriously delusional to think GSP can take enough of Silva's strikes for 5 rounds to get those takedowns. What is he even going to do if he gets there Silva would completely control his body with his superior strength, bjj, and long limbs.
Right, because GSP has been rocked so many times in his career. Like that one time with Serra hitting him on the back of the head.
It's not like he's ever banged with other powerful strong hitters like Alves and BJ and come out on top. Guys with much better TDD than Anderson, who GSP could take down faster than snapping his fingers.
After all, Anderson's TDD is so much better than NCAA champs like Kos and Hughes who've trained their whole lives to keep from being taken down. Such a stellar TDD that it took almighty guys like Lutter, Takase and Otsuka to take him down, let alone Sonnen, Okami and Hendo.
Silva's size won't count for squat, obviously GSP will only take this fight after he puts on some serious muscle. And for all his power in striking, Anderson is lean and weak in terms of grappling muscles. I've never seen him reverse or overpower someone on the ground. He relies mainly on his long legs for triangles, or dazing people while standing and jumping in for chokes as a formality.
It's possible that Andy utilizes his BJJ and gets a sub, but it is equally if not more probable that GSP rides him out or passes his guard repeatedly for a dominating GnP decision like he's done to MUCH better world champ level BJJ guys and grapplers like BJ, Serra and Karo. The only thing Andy has above these guys in terms of BJJ is a size/length advantage, other than that their creds are far superior.
If GSP is dumb enough to stand with Anderson for an extended period, then of course he will end up on the highlight reel like anyone else. If there were any doubts there Anderson cleared them tonight and put an exclamation mark next to it. But I doubt GSP will be that stupid, considering how perfectly he gameplans against his opponents' weaknesses.
