It's clearly GSP. People can stop with the Hendricks Dec now. I don't think Jon would have much fun going up a weight class like goat st Pierre and being a double champ.
Jon Jones was never finished by a guy who was 6 inches shorter than him in the first round in his first title defense. GSP left the sport at 32 and Jones is still dominating his division at 32. Come on man, do you even think before you make such threads?
Mayweather still the GOAT and he has wins like It'll take a lot more than a dodgy judge call to take Jones's rep.
