I found this article very illuminating. Yes, it is another example of a BJJ practitioner using his skills in a self-defense situation. But, take a good look at the article.
1) it was his BJJ skill against a KNIFE. Most SD gurus like to talk about BJJ not doing much weapons work, and will say that is a great weakness of the art, and when someone who relies on BJJ meets a weapon in “da streetz”, they will die. Not only did that NOT happen here, the BJJ practitioner came out if it unscratched, protected a third party, and did little harm to the attacker. All things that according to “experts”, should be impossible. And yet it happened.
and 2) take a look at the picture of him holding down the knife wielder. That is a position that is almost never used in BJJ – not because it is not effective, but if you do it to your training partner, he will probably get pissed off. So it is a street oriented technique that is rarely practiced, and again, the experts will say that means the BJJ player will automatically and unthinkingly revert to only things regularly practiced. And once again, the experts are proven to be ignorant. This person did use it under pressure, and did so effectively.
And here is the topper to all of this. The person is only a blue belt! the first level of promotion. Not even considered that high level in BJJ circles, and he still performed under stress effectively. For those who have an open mind, and understand critical thinking, this should be deep food for thought.
