I'm hoping some of you can dispel a myth, or indeed endorse the truth,
So, hitting the mandible from almost any angle with enough power will illicit a knockout. Great.
I don't fight full contact and I've been lucky enough to avoid nasty situations since leaving school. I've never KO'd anyone although I've "buzzed" people with a knock to the mandle and indeed with strikes to the temple, occiput and so on.
I watch MMA. The comentators talk about "one punch knockout power" and we see fighters taking strikes to the jaw with little effect. How likely is it that the average Martial Artist could achieve a knockout via a single strike to the jaw? Assuming it's a clean hit, of course.
