"It's five rounds with Nick Diaz. That's a long time to have that guy in the cage with you. Three rounds is long enough, five rounds is very tough. I know GSP is a great athlete, he's a great black belt but Nick Diaz is an animal. I think that's going to be the biggest fight in the history of the UFC, I really do."

Whether or not you think Nick Diaz never even should have been removed from his UFC 137 main event title shot against Georges St. Pierre to begin with, the two are set to scrap once again on Feb. 4, 2012. That's Super Bowl weekend and thanks to some well-timed trash talk from Diaz that has St. Pierre as animated as he's ever been, Cesar Gracie believes this will be the biggest fight in UFC history.
