I think Prime Fedor destroys Hendo, Werdum, and BF. The can crushing led to being lackadaisical. He could put his arms down and offer his back no problem can crushing. The same stuff Jones has down for the better part of a decade. Something he can't at hw which I still don't believe he can. He isn't competitive anymore at lhw without corrupt judges interference.
2004/05, there's no hw I'd bet on over Fedor. I'd pick him over Francis and Gane even today. After 2005, it was a gradual decline and even aesthetics, you can see a significant difference he was never gsp aesthetics. He had like a strong man power lifter build. Got more chud with time.
Disappointed he never fought SF champ Reem.he likely would have won by KO. Reem is good but chinny and not the best defense. Unfortunately, Fedor went on a losing streak. Similar to Silva, Jones or other greats.
Once that down slide begins, it's game over. McGregor looked good sparring but fighting after that catastrophe injury and the years of partying? Not likely. Here's hoping for another run.
