1. Georges greased against Penn
2. Werdum will smash Cain standing, in the clinch and on the ground again.
3. None of the examples you listed are good examples when comparing Cain/Werdum
Well, first fight Penn eye-poked GSP, second fight GSP greased. Neither of them had a reason to complain about the other's cheating.
And after two fights where both cheated about equally (greasing vs eye poking is a wash) GSP came out with two wins, though the first was razor close.
Agree that other examples are irrelevant; since when does MMA math apply to this sort of thing well?
