A better question is what the hell is he smoking with "better stand up". One lucky punch on GSP and suddenly Sera is a top level striker? LOL. He's had one KO in his whole freaking career. That's a 7% KO rate. Hughes has almost a 30% KO rate, four times Sera's.
I could whoop Matt Hughes standing. With my hands tied behind my back, blindfolded, with a werewolf sodomizing me.
