"Street fighter with no credentials"???? *cough, cough, cough*. Think again, my friend.

This is a fight between BJJ black belt, MMA fighter, and UFC former champion Royce Gracie and Five Animal kung fu teacher and now 34-21-1 MMA fighter and BJJ practitioner Jason Delucia, taken from one of the Gracie Jiu-Jitsu in Action videotapes.

As a BJJer myself, I intentionally didn't sift any of these challenge matches, and I'm not sure how I'm going to vote yet. I believe that BJJ fighters standing out in high-level MMA competitions through their superior groundwork skills is far more convincing of BJJ's effectiveness than these clips from the BJJ in Action tapes, which amount to little more than propaganda films.

Not to mention, nowadays, these kind of things tend to give BJJ a bad rep, not a good one.

Yikes.
