I was rewatching Liston-Williams 1 yesterday, Cleve was so qucik and explosive especially when he was doubling and tripling up on that hook. If he had Liston's chin I wouldn't be surprised if he went further than Sonny.
I'm surprised you didn't include footage of him knocking out Otto Von Rentchterner, who was coming straight off his own impressive KO victory over Indiana "Big Hat" Jones.
