Fedor is one of the best ever, no tarnish to his legacy whatsoever....so what? he lost after a decade of dominance and is suffering from what EVERY fighter will eventually come across....the decline of their dominance and/or deteriaton of their skills.
He's still the guy who survived getting slammed on his head and won, the guy who beat CroCop, Big Nog etc etc etc. some of those fights are part of MMA legend...
...just my view...and I don't even like the guy!
