I think so Haye had him wobbled with a right hand so on that basis I think Wilder could one shot Valuev
Even Barrett briefly stunned Valuev. So its possible especially since we never really saw Valuev in with a killer puncher, but the longer the fight goes on Valuev will start throwing sloppy right hands and pressing his weight on Wilder not unlike Barrett.
Gassed? He hardly anything other than plod forward slowly throwing tame 1-2`s, looked like he was in slow motion or half asleep.
imo Wilder has a 75% chance of breaking his hand on Valuev's face (he broke it several times against fighters less chinned than Valuev) , people don't realize what thick of a skull Valuev has, he has a medical condition that causes him to have excess HGH. HGH is known for giving boxers a super thick skull but boxers take it in limited amounts as a PED as not to get caught. Now imagine if somebody naturally developed with HGH at high levels. I really think no one could KO Valuev. I think it would have to be either Wilder wins by a TKO on a bad cut or Wilder boxes him to a 12 round decision with Valuev winning maybe 2 rounds or 3.
What about Oliver McCall? If anybody could take Wilder's power without going down McCall would be a name you would have to consider.
McCall's iron chin mith begins to be a bit overrated. He cried in that pitiful way because he knew Lewis would have destroyed his mandible and all that was above it like he did with Rahman maybe worse. Lewis intimidated him so much that he noticed soon drugs he usually got to reduce pain and anxiety couldt work with that Lennox hungry of revenge.
