Even including Russia, Im going to stick with Crocop. I dont want to say "Fedor was never that good" but I always felt he was a bit overrated. Had he fought in the UFC (drug testing) then Id give him the nod. Not that Crocop was clean by any stretch of the imagination but he at least had a UFC run. Much like Wandy, Fedor benefited from favorable matchups. Big Nog was a good win but fatass Ricco Rodriguez beat Big Nog in Japan and was robbed by the judges.
Dude has made an absolute dick out of himself in recent years but I don't see how it's not Conor.
