I'm watching the Hunt v Nishijima fight right now. And I can't help but recall a discussion that we had in the Ask the Trainer section a while back. The orignal poster was trying to convince people that "all chins are created equal" and that there's no such thing as a person who has an unnatural ability to take a punch.... well, this fight is a textbook example of why the original poster in that topic is absurdly wrong. Mark Hunt is among the hardest hitters in the world... he has got to outweigh his opponent here by 50-60 pounds and has repeatedly snapped the guys head back with punch after punch after punch... I've never seen someone take so many "knockout punches" and keep coming back. I have a feeling Nishijima is going to fall eventually, but so far, he seems to have a chin made of titanium or something... excellent fight so far.
