I wondered if anyone can shed light on this for me. I've been watching MMA since the first UFC. I see guys get caught square in the face with flying knees, kicks, elbows, and forearms smashed repeatedly on someone's face with their head on mat, thus, absorbing the full impact of the blows. I saw heavyweight monster Ngannou nearly decapitate Overeem. Its taught me that generally the human face can withstand a lot of punishment, more than I previously thought when i was a kid. Usually there's no more damage than some bruises or a broken nose, and occasionally a broke jaw, orbital bone, or cheekbone and that's usually after a lengthy beatdown. To my eye, the punch that Cosmo hit Sage with didn't seem particularly noteworthy, and it was ONE punch. Let me rephrase...it was a beautiful punch and I can see how it was a fight ending punch, it just didn't seem like enough to disassemble his face the way it did. Sage's head was able to recoil with the punch. It wasn't trapped against anything. Sage had eight facial fractures and thirty bone fragments removed and suffered nerve damage as well. I just wonder if he had a more delicate bone structure than most or if Cosmo hits harder than Ngannou.
