Well, Wilder couldn't drop Johann Duhaupas (who has inferior chin to Wach) with nearly 1000, maximum-powered flush land punches. So based on that, Wilder lacks the power to even dent Wach.
Anyone could be stopped by anybody if the referee stopped the fight. I think Wladimir Klitschko may very well have been the first person to KO Chuvalo. Wladimir Klitschko > anybody Chuvalo has taken punches from.
Lol. Any modern day power punching heavyweight > George Foreman. George Foreman is a myth and is grossly overrated! Foreman wouldn't even impress an actual modern day power-punching super-heavyweight.
