The winner! Out of past fighters, "Two-ton" Tony Galento and Joe Frazier wasn't the most toned fighter in his prime.
joe calzaghe was built more like the average footballer than a boxer larry holmes no body beautiful peter buckley= 300 fights v every british prospect from 122 to 140 all to points looked like the milkman but was tough.
You're right it's very rare to see that. I can think of a couple though. Monzon, Yaqui Lopez, Lara, Canelo. And when you do see a latino with a muscular build they usually don't look indigenous.
