I'd love to see a good brawl but the chance of Georges stomping Nicks ass is much more probable imo. Bigger, stronger, faster, more skilled, and loads more athletic.
Tbh, I figure this fight will be as lopsided as the Rory vs Nate fight if not more. Nick will look like a frail child once GSP starts throwing him around is my prediction. Pierre by tko in rd 4.
