it's obvious i've never seen any of them fight because i explicitly said the fact that they might beat Manny doesn't necessarily mean they rank higher on the all-time list ?
And I see almost no way Rocky could get inside that reach or overcome the size and strength disadvantage. He was what, 5'11" and 185 for most of his career? Even if he did, Vitali's chin is a rock and doesn't break from the first haymaker that lands. I guess he could suzie q Wladamir if he landed flush but it seems unlikely.
