This isn't a p4p skill list, but an athletic or explosive athelte list. For me. 1. Roy Jones Jr 2. Manny Pacquiao 3. SRR 4. Mike Tyson 5. SRL
Ken Norton was on the Football team of the Marines when the Vietnam war broke out. When they started sending team members to Vietnam Ken Norton got on the boxing team. He looked like a bodybuilder before PEDs came around, as far as I know.
John Conteh was pretty good athlete he did well on Superstars didn't he ? Others that that come to mind.... Evander Holyfield = Beat Carl Lewis in 800 m charity race. Ken Norton Muhammad Ali
The first two that spring to mind would be Roy Jones & Mike Tyson. In terms of boxers who could easily turn there hand to other sports or had freakish ability (e.g. sprint) I'll thrown the below names into the mixer. Anthony Mundine Sergio Martinez Ken Norton Anthony Joshua Katie Taylor
Michael Grant, back in the 90s, 2000s looked like a tank. So did David Haye, as far as for the not obvious ones that have been mentioned.
Tyson Fury He is the new meta of heavyweight. No man of his size past or present has his stamina and movement for his size. and he will be the only man in history to have walked through the abyss and Wilder's right hand coming out the other end to tell the tale.
If i get your question right and you are not asking for 5 best boxers but for 5 most athletic bodies than : 1 mike tyson 2 wilder 3 aj 4 holyfield 5 wlad There will be further in lower weight classes.
Frank Bruno was more muscular and ripped than all of those guys. Tyson doesn't even make the top 50 in reality.
