He would have wiped the floor with everyone just like he has in the UFC.
Crazy how some people talk about his ground game like he's one of those guys who can't do anything down there an just stalls. There's a big difference between guys like Rashad Evans, King Mo, Guida etc and GSP. GSP is always effective, he just isn't good at finishing. But he does beat the snot out of whoever it is in most cases. Only against Hardy he didn't do much GnP but he was hunting a sub, only his jits wasn't up to par that night.
I can't wait till he does the same to Diaz too, it's going to be great.
