Likely Valuev, just due to natural size & bone structure. Others could be more weight trained/muscle per square inch & certainly defined, & broader for their height, but with a 52" chest/55" expanded 21 1/2" neck likely it is him.

His wingspan isn't too big for a man of his size, he's either got narrow shoulders or short arms. Anyways the man don't count, same goes for Carnera. They both appear to have suffered from some sort of gigantism to me.
His reach is equal to his height. Most boxers have unusually long arms for their height compared to normal people.
At 315-325 lbs how could it NOT be Valuev....:deal As big as he was he didn't have a punch to equal his size...
Liston had huge shoulders, he made Ali's look narrow in comparison. If the stats are true then his wide shoulders would contribute to making his wingspan so huge.
foreman had clearly wider shoulders than bowe, or baer, and in a video he is next to lewis and he looks wider than lewis too, carnera was a giant, liston is similar to george, shavers was wide for his height but maybe he looked wider than he actually was because his height
Narrow only compared to his upper back muscularity, not for an average man & maybe average for a HW. Just like FJ is correct, Valuev is average in wingspan ratio for a regualr man, like I am 6' X 6', boxers tend to be longer than their height.IF Valuev has narrow clavicles it is only for his height, huge for a regular guy. Though that could preclude him from being a candidate for the widest. Though I do not see him as even relatively narrow. Of course gigantcism counts, as would Butterbean's obesity: the question is structural size, not what the cause is or body composition. If we counted these things out-which would be another question-then I think many of those above would be candidates. But it would unlikely to be anyone shorter than Foremean, & may end up being some obscure boxer over 6' 6" & heavily muscled &/or fat.
What is gay about talking about the muscular dimensions of fighters? Maybe you were thinking about some other kind of muscular dimension...
