I have a few friends who are into the whole gracie combatives thing/self defense thing (train at a real gym) and they assure me that sport jiujitsu will not translate to the street well because you don't have to worry about punches. While their is some truth to that statement, I don't think you should totally rule out it out. I mean, if you were drunk and this black guy was hittin on your girl, and you know your babe's into the interacial thing, and you tried to attack him, but oh shit it's Jacare pre-mma, i'm pretty sure he'd fuck you up. But then theres also the argument that because he's so athletic he'd have the upper hand. What do you think?
