Liston in 1. No heavy with an only average chins and limited boxing abilities stand a chance with the bear, no matter how hard he hit.
That's it in a nutshell.Far more interesting fight woulda been Cleveland (Big Cat) Williams against Earnie Shavers.Two big bangers,with not so great defense or chins.
This is like asking who would win if a great white shark fought a moose in the middle of the ocean. On land the moose would have a chance, or in the case of Liston-Shavers "on land" meaning if Liston's arms were tied behind his back and he had LSD injected into his eyeballs. But in the ocean, not a moose's natural habitat, (they aren't good swimmers) the shark would win. I doubt this analogy made any sense, I wish I could say I was high and leave it at that.
