Don't you ever put some overrated MMA fighter in the same sentence as the greatest. Ali was still a world champion at 35, while Fedor was getting beaten by WWs like seven years older than him. Ali looked great even at 40, for a 40 year old or even a 30 year old.
Fedor looks like exactly what he is. A 40 year old overrated fighter that can't even get past his fellow senior citizens. Don't talk to me about age little man. Fedor is the same age as practically everyone in the top 5 today.
Fedor has been exposed for what he is though, and everyone under the age of 50 that doesn't have stolen pride dvds from blockbuster knows it. The only reason Fedor dominated is because he was the original Ronda Rousey. That's all he is, a guy that fought in an undeveloped era against sub par talent (which still sub-par at HW even today), to which most of he still didn't even fight. Who knows if PEDs, or fight fixing was involved too in that criminal organization as well. What is certain though is as MMA evolved and Fedor faced better competition, his mediocre blitz you striking style was exposed for what it is.
Fedor is still a pioneer of the sport, and thus a legend. His contributions to MMA were vast, but a GOAT or even being consideration for, he is not. Anybody with a tiny sense of a brain instead of one filled with nostalgia and fandom knows this.
