I did see the fight - I also saw their first fight. I have seen every fight of both fighters. Something was amiss because NOBODY, has ever dominated BJ like that. BJ tore St.Peirre up in the first two rounds of their first fight, and almost finished it.
If you watch the clips, BJ was trying to lock in his rubber guard and his legs kept slipping off St.Pierre. Other fighters have said the same thing. Something was wrong.
I disagree, vasoline is a major factor against a fighter like Penn who uses his superior BJJ and flexibility
