I suppose that Hapfur Bjornsson is the strongest man ever to box, if you have to answer the question literally.
Saensak Muangsurin colliding with Hector Thompson would he a tremendous meeting. Two of the strongest fighters ever IMO.
They were not huge by modern HW boxing standards, not at all man. Dokes, Tillis & Tubbs were not the biggest of the 1980's in muscular weight, they would weigh less-but not dramatically so-at the same bodyfat level. But others had as much or more muscle per square inch than Weaver & Holyfield. Tyson was not at all much more body fat in his prime, but weighed as much as the heaviest Holyfield, & more than Weaver-why is he not the strongest guy out there? Holyfield even with all the PEDs/steroids carried less muscle, in part because where you normally carry 60% of your lean mass, the lower body-he was always relatively thin. 22" thighs & 13" calves. Even so the only upper body measurement which was large *for* a modern HW was his neck-the area (around the traps) where steroids tend to bulk up dramatically. Forearms fairly small. Weaver was definitely muscular, but in overall mean mass he was on the high side for the era. His upper body stood out more, like Norton. If you compare him to say Tua or Frank Bruno (247 cut vs. Tyson) he had less muscle mass for his height at the same body fat. They were in all likelihood stronger than Weaver-& hit harder (although this is a coincidence).
I would say George Foreman, but Dwight Davidson was strong at middleweight. I could see him giving Hagler a couple of uncomfortable moments in a fight before losing a UD.
I don’t recall him manhandling Tony Sibson. Although to be fair Sibson was a bit of a bull himself.
I'm not aware of it, to be honest. I can recall some prefight chatter about Clottey but nothing specifically about his strength. I kind of want to go back and watch some Tackie/Clottey fights to see.
Jorge Ahumada deserves a mention too, John Conteh said he is both better than Saad in terms of chin and strength.
