Surprised that no-one has made a comments about PEDs yet. I think both were on something. Still made them a lot more than even a lot of gifted athletes could hope to be with or without that help though. I'm going to go with Pac. He destroyed elite opponents that were much larger than him. That's more impressive than a flashy combo in my book.
Close..... Roy was faster more powerful single punch puncher PAC had superhuman stamina he just never stopped. Roy started slowing down and fighting in spurts, resting on ropes/corners at age 30. Pac was also stronger P4P Roy was smarter, Pac was tougher
I would probably go with Pacman who needed more athetism for his style. RJJ didn't work with a jab BC he used awkward angles with a far taller body frame.
Who are these elite fighters that were larger than Pacquiao that he destroyed? Miguel Cotto, who was forced to come down to a catch weight? Ever seen RJJ vs John Ruiz?
RJJ without a doubt. Pac was put to sleep and beat more than once in his prime. Roy on the other hand was utterly untouchable and put nearly everyone out.
Roy. A thoroughbred genetically, trained spartan-style by his sadistic pops and bursting at the seams with primo, grade A dope. He was a sight to behold in his pomp, unique.
He couldn't take a punch. RJJ and Pacquiao are the 2 most physically gifted fighters of the last 30 years. They are also the best fighters of the last 30 years. That said Pacquiao is the most physically gifted fighter.
