depends on how they said it....again Tyson was not a real one punch KO guy....Except with some of the really no good bums from the early years...Mike hit damn hard but speed and voulume had a lot to do with it....If you remember once Mike started to become a head hunter the KO's came less frequent'''..Tyson hit hard in every punch but being a hard hitter and one punch KO guy are different...Foreman and Shavers were 1 punch KO artist
