Hmmmm, good point. I’m going to have to say, it would come down to circumstance. Basically whoever connects with the first punch would win. I can see chuck coming in with a nice HHWWWAAAA to the neck. If he connects, game over. Kimbo no longer has a head. If he missed though, I’d see kimbo coming back with with a power hook that would take out Norrris. Then Kimbo would feast on the legend.
If Kimbo struck first, Norris would be ready to pull out a dodge that would be so fast and text book perfect, that kimbo would be disoriented and go down with hardly any fight. Again though, if he did connect, game over. That guys a power house.
