you dont see a difference between a guy like nog and a guy like cain?
Other than Cain, Dos Santos, Overeem and Cormier it doesn't really become debatable. The fighters I mentioned then it's debatable. Fedor lost to Bigfoot, Werdum and Henderson those opponents don't represent a higher standard to me. Henderson is great but he's not a heavyweight.
Cain, Dos Santos, Overeem and Cormier then it's possible they are of a higher standard. Even then it's hard to say.
