I agree with a lot of what Seamus is saying. But who was a one-punch KO puncher ?


Even in (or especially in?) heavyweight boxing, it seems that the opponents tend to get up a few times.
And you have to hit them a few times. Even if you are known as a 'puncher'.
Unless you're up against someone who's grossly out of shape or doesn't want to be there, it's unlikely to be a 'one-punch KO'.

Foreman, Tyson, Liston, Marciano, Dempsey, Louis, Lewis, Baer ... opponents often took their punches and kept coming in for more.
