Wilder might be known as the chinniest of the top heavyweights and he hung his chin in the air all night and it took quite a few flush shots and he was stopped on his feet. Fury has below average power I'd say
It's nothing like that. Tyson was a genuine KO artist, Mayweather wasn't. If Hatton hadn't twatted his head off the turnbuckle, then that punch wouldn't have done nearly as much damage. Tyson would have always stopped Spinks.
Surely you see my point though? Mayweathers punch sent hattons head into a part of the ring. Spinks might have been able to get up from the final knockdown against Tyson had the back of his head not hit the canvas. Both are inconsiquential as both fighters were on their way to getting knocked out regardless.
Ivan Calderon reigned as king at 105 then 108 for quite a while. Second-best 105'er ever. His KO% would indicate among the most feather fisted to be so successful.
