People confuse losses via DQ or wins being overturned with actually losing a fist fight. You can argue that Jon should have lost close, competitive fights, but the cold hard fact is that no one has beaten him in the octagon. In this sense, he is 100% undefeated. If this is your GOAT criteria, than Khabibi is the only other guy in the discussion. Unfortunately, Beeb’s record includes 16 cans on the Russian circuit before coming to the UFC, most with no wiki. Jon was in the UFC after 6 and fought for a title after another 7.
If you’d like to compare long, unbeaten streaks with losses that came before or after, then yes, Fedor, Igor, and Barao are worthy of considering. I have Fedor and Jones as 1A and 1B. No dispute there.
I place Igor in that “greatest that never been champ category”, and Barao as a top BW GOAT. I don’t need to dissect why neither of them are in p4p GOAT discussions.
Resume:
-Hendo is in the aforementioned Igor category. Lost and finished multiple times in his prime. An all time great that is one of my personal favs, but not a p4p GOAT.
-Fedor; again, no argument.
Differentiation:
OK. Jon had phsyical advantages, but he knew how to use them. Height and reach mean fuck all if you can’t put the rest together. There’s a reason that a guy like Struve isn’t in this discussion. Saying that Jon can’t be GOAT bc he had physical advantages comes off as desperate and deranged imo. Worst point you have made so far. Age? Not Jon’s fault and out of his control. People say the same thing about Stipe.
GSP? Again; no argument. If you place GSP over Jon, I don’t consider that wrong or far fetched.
Will address the second half later.
