The kung fu VS MMA debate. that is a BIG worm can. have fun with this one.
Imo I think 1. somepeople feel they have nothing to prove. 2. some peoples skills really are not as good as they think. 3. others feel the few rules that are in mma will take away from their ability or bag of trick if thats what you wanna call it. Personaly I've never seen any kung fu used in UFC / Pride.
I't seem like it's gonna be a decent converstion. but... well you'll see
"All the skill in the world won't hold up to a real confrontation if you are too afraid to use it."
