Liston, i'll say it again, didn't look to me like he ever landed one clean punch on floyd, yet and still it was enough to put him away in one round. It's possible that Ingo landed a harder right hand and that he was a harder puncher with that one punch, it's also possible that he just caught patterson cleaner, which is what i think. Patterson had no chin and how can a man even remember exactly how hard a punch was when he's out anyway? Cooper said Patterson him him harder than anyone ever, that it was "lights out" as soon as he was hit. It's rare for top fighters to get hit with those kinds of shots but they do happen.
