That’s a very tough question. I’m sure it’s possible but in most cases unlikely. I would give Lennox Lewis a shot at it. Possibly Tyson fury and Vitali Klitschko, not because they’re great punchers but because they have the size and styles to make it happen. In any case it might not happen
Klitschko brothers Lewis Foreman AJ Wilder has the potential to, but he might get stopped before it happens. Haye almost pulled it off, I think if they had a rematch he would’ve stopped him late.
Is there a limit to this question, because I can come up with 20-30 just off the top of my head. Basically everyone not named David Haye. Holyfield was past his due date when he fought the Hairy Russian, otherwise he would have KO'd him.
Think a young Foreman would bludgeon Valuev to the point that the doctors stopped the fight, the giant may have had a cranium and jaw of granite but his face was still capable of being turned into a bloody mess. Liston and Lewis may well have done similar.
I think Corrie Sanders might do it. They actually sparred together and apparently Sanders gave him a boxing lesson.
Tyson, Louis, Wilder, Baer and Foreman for sure. Lewis, Shavers and Wlad all definitely have the power to, dunno if they'd fight the way they'd need to do get it done. I think Lewis would, given how aggressive he got with taller guys. Shavers probably doesn't have the gas tank. Speaking of which, Marciano probably clubs him down. Wouldn't surprise me if he didn't get a stoppage though. Dempsey and Frazier could do it too, but same again. Sleeper pick, Ingo. I think he could definitely start fast enough to take Valhalla Val out.
