"The truth was that Phil put Vaseline on [St. Pierre's] face. We have this little breathing drill that we do. ... And so after he greased him, he went around (to his back) and did that drill. So everybody was like, 'He greased him.' But that couldn't be further from the truth. Phil would never do something like that on purpose." - Greg Jackson
It doesn't matter if it was voodoo or not. If you have Vaseline on your hands, you cannot touch a fighter anywhere but on his face. Nurse touched and rubbed St-Pierre's back, chest, and shoulders. It's against the rules.
I hope the Nevada State Athletic Commission forgets all the nonsense and concentrates on the spirit of the rule, which is to protect fighters. Whether it was intentional or if it prevented BJ Penn from sinking in a triangle really does not matter. We'll never know those things. All we know is a rule was violated repeatedly and the cornermen should be punished.
