Thanks for the input guys. I really do think it is a mental thing. Being a wrestler, I have always tried to keep my neck in shape and strong. I was wondering, do you think that really plays a role in being able to take a punch. I was trying to think of some pro boxers who have a big neck but a glass jaw and I can't really think of any other than maybe Klitchko. although I think his is more or an endurance thing.
