Fedor accomplished something incredible. 10 years without a loss. 28 fights without a loss. His best wins are Big Nog and Cro Cop, both in their primes.
...but there are other truths that are overlooked.
He fought an enormous number of non title fights in Japan, against men who had no business being in the ring with him. Yes, he beat bigger, stronger men at times, but they were men he was supposed to beat. They all had far lesser skillsets than he did.
Of those 28 fights, how many were against anyone of note? I count 11. Babalu, Schilt, Herring, Nog1, Coleman1, Randleman, Nog2, Nog3, Cro Cop, Sylvia, Arlovski.
Hunt had no business fighting Fedor at that time, just as Coleman did not the second time around. Gary Goodridge? Really? Matt Lindland? These are not fights that a fighter of Fedor's stature deserved .
Early in his career in RINGS, he had an enormous amount of difficulty with Arona, and arguably should have lost a decision to the much smaller fighter.
Fedor accomplished a lot, but he fought a ton of men who were put in front of him to be crushed, and were not acceptable competition.
