Does having an Iron Chin shield a fighter from brain damage?

no, but avoiding getting hit will

 

I always thought Havin an iron chin would make it worse?? Atleast if your made of glass the 1st decent shot and your on the deck
If you jus plod forward and block every shot with your face I don't care who you are it's not guna be good for your health regardless of who you are

In sayin that the more times you get ko'd and the more concussions you receive I think that'd be much worse ..... In short I've no idea lol

 

The exact opposite.

A lot of fighters that are known for having a iron chin clearly show braindamage at the end or after their careers because of taking punches that would have knocked out other fighters and just fighting on.
It also looks to make them stretch their careers for too long... because of the "he only outpointed me, I still got it" sentiment, while it just was their chin that kept them up.

 

Bone density plays a critical role, ie. the thicker the skull, the more protected the brain, and the more punch resistance. Can't train for that...

 

Well I don't know really since Enzo has the glassiest chin alive he should speak clearly but still speaks like a drunk.
