I can't think of anybody else that has taken worse beatings and not only keep on fighting but win. He is badass for sure but i would like to see him hang up his gloves....i afraid he is suffering long term damage at this point.
For fights *in the ufc*, probably not. But with Pride, for sure. Fedor, Sapp and CC almost killed him, and he managed to win two of those.
Diego can take a beating.
Nog is tough, but people in this thread forgot about Nick Diaz, Glay Guida and Roy Nelson
