Fedor by far has the worst resume out of all these fighters being mentioned. Never beat a well rounded fighter, beat old one dimensional relics from the 90s and his best wins are still opponents who were one dimensional, and his record is Littered with cans and freakshow fights. All of a sudden that "decade streak" amounts to very little in the grand scheme of things.
The big 3(Jones, Silva, GSP) did not have pro wrestlers/freakshows, no-names, guys with almost no fights right in the middle of their streaks to extend the longevity.
The bottomline is Fedor fans had their creative way of using propaganda to make him appear as the GOAT. This did not hold up as people started seeing through it.
