LAS VEGAS -- Gone is the polite Georges St-Pierre. He's been replaced by a guy who has demons in his head.
If anything shows St-Pierre means business about wanting to rip Nick Diaz's head off down the road it was the fact that he sat down with the media for close to an hour on Wednesday. That's when St-Pierre dropped the demon line and talked about having lots of street fights in his past. Diaz is the only bad egg in the UFC's welterweight division.
