Well it depends what you mean by 1 punch KO Scenario 1 Single shot KO before any other knock downs in first few rounds scenario 2 Single shot KO in the late rounds after dominating opponent but not knocking them down scenario 3 they are beating the **** out of the other knocking them down earlier then 1 punch KO'ing them (any round) sorta like hatton pac style scenario 4 they are dominating there OPP in middle late rounds then they get 1 punch KO'ed scenario 5 very close fight going into the late rounds then 1 punch KO scenario 6 1 punch KO in the first round there are more lol each 1 leads to different reactions
It depends on what was happening in the fight before that one punch connected to end the fight. Was one fighter getting there ass kicked before the one punch landed or was it an even fight then all of a sudden BAM? Was it a back an forth up and down battle before it happened?
