A) '60 S. Liston vs '23 T. Gibbons 1) Shelby MT, 15 rounds, 1923 2) Seattle, WA, 12 rounds, 1960 B) '23 J. Dempsey vs. '60 E. Machen 1) Shelby MT, 15 rounds, 1923 2) Seattle, WA, 12 rounds, 1960 Dempsey vs. Liston comments, and T. Gibbons vs. Machen comments, also welcome.
Liston would knock Gibbons out, probably batter him around and bust him up for a few rounds with the jab, then KO him in 6 or 7 rounds. This version of Dempsey was rusty so he might have to go the distance with Machen as he did with Gibbons. (I'd expect a PRIME Dempsey to KO him quick though)
