People have been asking this question for as long as I've been training: Does BJJ prepare your for street confrontations? It's a good question, especially since we both know ever since you started training (6 months ago), you've been walking around with your head mighty high. We wouldn't want you to have to back any of your training up without first understanding some critical stuff. You clearly need the Brothers Gracie, Rener and Ryron, to primer you for 22 minutes on the importance of distinguishing sport from street Jiu Jitsu. Exactly that.
This video, although sort of an advertisement for GJJ and its "Gracie Combatives" system, is informative and raises good points. It's true that many of us spend a lot of time and effort perfecting techniques that are not valuable in a self defense or street fight situation. Hopefully, most of us know this, and have the wherewithal to develop general combat/fighting skills that we can apply to all that mortal combat and battles to the death we participate in on a regular basis.
Seriously, good stuff from Bros. Gracie.
