Dude, it's as simple as this. Rounds 1 and 2 were close. Round 3, Sonnen blew Bisping out of the water.
Your opinion is your own. But to say that the only clear cut round in that fight didn't go to Sonnen is just plain, old bias. And to be honest, I have no time for that. I gave Mike full respect for bringing the fight. But round 3 speaks louder than a razor close round 1 and 2. There's really no disputing it.
So, yeah. Number 2. Assuming he smokes Vitor, which I suspect he would/will. Granted, I'm also a Vitor fan, so I'd not mind either man walking away with his hand raised.
