Would have to be Ali Raymi... ktfo'd everyone he faced in and around his weight, so he had to start getting in there with heavyweights. He tko'd Odlanier solis, Wach,reports of McCall,and numerous other heavyweights. Any other mentionables oit there?
A below-average pro called Johnny Walker Banks used to routinely bash up Hagler, Spinks and Qawi in the 80s. He made his living as their sparring partner.
Jersey Joe Walcott was Joe Louis's sparring partner then he ended up challenging him for the heavyweight title.
He fared pretty well.. Re. Raymi, I just find it astounding a Minimumweight is knocking out heavies with granite chins. It's unreal. Too bad his full potential and s****om weren't realized
That's what happens when you spend most of your time with your head up your ass. Come out once in a while. And exactly how did you even know I was going to post
