Some dudes are born with good chins but that doesn't last for ever. Protect your brain, it can't be replaced or fixed.
That's what I thought.
The reason you get KO'd is from that neck snapping motion. Problem is, physics is against you because your neck won't be strong enough to withstand a legit punch that lands on the button. If genetics has blessed you, having a short neck and square jaw helps you a lot (think BJ Penn). Having a long neck and pointy chin makes you easier to knock out. Passini is right. Best to learn how to roll with punches. Getting dropped with a straight doesn't mean much about your chin. You just got hit on the button. Lotta guys get dropped with straights. Jonny Hendricks KO'd Kampmann with a straight. Strengthening your neck is good. But it's not a surefire way to avoid getting KO'd.

I'll try and find the article. If you played football in High school you may be well on that road. It is fairly well accepted that your first concussion is the hardest to get. By the time you have had 3-4 it is pretty easy for you to get the next one.
To be fair, Brock never got KO'd. He just doesn't like getting hit. His chin was fine. His heart wasn't.
