OK, let's reverse this.......who outside of the UFC, besides Barnett, is worthy of fighting Fedor?
Is he going to spend his final years claiming to be the best while fighting in high school gymnasiums for 30 people against some drunk hack?
There are a lot more fighters outside the UFC capable of beating him than inside it. Barnett, Hunt, Aleks, Sergei are all better fighters than 99% of the UFC HW's. And none of those guys are on his level.
I don't know why people want to see him fight Nog again. Nog is still great, but he looks like nothing compared to what he was like when he was the Pride HW champ. He's older, slower and not as dangerous now. Who the hell wants to see him fight Nog again? He's fought him 3 times, and absolutely destroyed him every time. No one gives a shit about seeing that fight again.
Funny how Sylvia was the HW champ, took the "Legendary" Couture to a decision, Fedor beats him in 37 seconds and he's apparently washed up.
There is NO ONE in the UFC that could hold Fedor's jockstrap and he would do nothing but fight cans if he were to sign there.
