Roy is the first guy that comes to mind. He was simply blessed with otherworldly athleticism and reflexes.
Wladimir Klitschko was a monster, if you doesn't count his below average chin and tendency to gas out.
Hagler and Foreman chins and temporal bones seem more thick than asphalt lmao Can't find it now but Ali's description from his physician that compares him to a greek, mythical god was so accurate. And Tyson? That body so young is simply insane.
I've often wondered this - Roy's stock was at an all time high after the heavyweight win. I doubt he would have walked away then... But perhaps after Tarver 1 - if he'd read the warning signs. I think a lot of people would have him top 15 or even top 10 p4p. His later career was sooo long - and terrible - that it's often forgotten how good he once was.
Jorge Locomotora Castro. World class from super welter to cruiser. It took a melted down heavyweight to KO him and that didn't happen until his 125th fight. It took a car accident to retire him. Legend.
Greb needs to be mentioned with that windmill style attack, aggression, and endurance. All footwork couldn't catch him clean, . 300 fights and that dominate. Must have been ALL athleticism
Don't see how it can be anyone other than Mike Tyson. In terms of genetics and physical attributes, he's basically just Roy Jones Jr but heavier and with a better chin.
