Wrastlin' is excellente!
But nothing prepares a person for a good punch in the face, like a good punch in the face. I think the same arguement could be made for boxing, as they get punched in the face a lot.
Truth of the matter is, a fighter has to be a fighter. Doesn't matter what background, wrestling or boxing, as long as the heart is there. Anyone can be trained to perform moves. Counters, subs, etc. But to fight is something very few people are naturals at.
