Shit, sorry about that! ^

GSP passes guard more often than not when he tries. He'd take the easy transition from side mount to north/south and rain down the knees. The only difference would be his number of stoppages. 183 lbs shouldn't be an issue, most Japanese fighters don't cut much, if any, weight, GSP wouldn't be at a huge disadvantage from size for the most part. Today's wrestlers would have mauled people in Pride. Guys like Coleman and Randleman refused to cross train properly, the only cross trained wrestler that comes to mind in Pride was Hendo, look how well he did
