Obviously you cant compare the boxers of old to the current ones in terms of who would win a fight. Thats completely unfair to them. Practically every current NFL team (still not sold on the browns, loins lol) would beat the 85 bears or the 72 dolphins. But you can only be great relative to your time. No one dominated like those two teams did which is why they are considered to be two of the greatest of all time and not the 2009 steelers. And to whoever made the jesse owens comment, i dont know what track you've involved in but owens name is still revered. Hell, the reason why usain bolt is being talked so such levels is because hes destroying everyone LIKE jesse once did.

Manny is great but he's nowhere comparable to robinson. Robinson dominated many of the sports all time greats and was 40-0 before losing to another all time great in jake lamotta in a rematch who outweighed him by 16 pounds. and he still ended up beating him five of there six fights. Where as many of mannys big wins/fights have question marks surrounding them. The very arguable draw and narrow win against jmm, the old weight drain de la hoya, i wont even count ricky hatton lol and is cotto even the same fighter since margartio and without a real trainer.

We can put manny in the same sentence as robinson when over 60% of boxing analysist and reporters give him first place vote of greatest of all time, when practically every other LEGEND of the sport says your the greatest of all time like ali, lamotta, louis and leonard. or when he beats people of the same caliber of basilio, graziano, armstrong, etc.
