Matt Hughes chimes on the Grease Gate via his blog:
Now, on to what everybody is talking about, the greasing. I’m not the only one who has said that GSP felt greasy during a fight. I know Matt Serra has mentioned it and, even in their first fight, I think BJ said something. I’m not saying GSP did something wrong and I’m not saying that it would have changed any outcomes of any fights; but what I am saying is, for my last two fights against Georges, he felt greasy.
