Re: Most physically powerful boxer...
James Toney. How the hell does a grossly overblown super-middleweight hold his own against most heavyweights? And it ain't just steroids. The guy is phenomenally strong considering what his natural weight ought to be.
Butterbean... at least for a few minutes before he has a heart attack.
No way Liston beats Foreman at any age, in their prime or not. Foreman was always naturally bigger and stronger. Liston's vulnerability was the robotic way he threw his jab. Leotis Martin timed him perfectly over Sonny's static, predictable jabs. Muhammad Ali's "phantom punch" in the rematch with Liston was also a perfectly timed right over a mechanical Liston left.
