With all due respect, there is little to no "facts-based" discourse going on, on this board. 99% of it is purely opinion. When I have an opinion on something, I do base it on facts. Like the fact that 2/3 of Fedor's opponents can be categorized as "cans" i.e. they have less than 5 fights on their record, or they've lost more than they won. So, relying on Fedor's record to call him the GOAT, if flawed, and that is a fact. IMO, some of his wins were fixed. That is not a fact, but an opinion based on the fact that Pride had mob ties and it has been proven that some fights were fixed. It is also a fact that Fedor refused to fight any notable opponents in the last 5 years. From that fact, a deduce that he was afraid of loosing.
In summary, Fedor was an overhyped mediocre fighter.
