I was just recently checking out these guys videos. They admittedly not BJJ black belts, rather JJJ black belts who have studied a ton of different arts. They have close to 200 videos on youtube describing many techniques. From the few random ones I've checked out, they seem to be pretty good and pretty accurate to how I've learned most of these techniques. Does anyone know anything about these guys? Are they legit grapplers despite no BJJ ranking? Do you guys think the techs they display are pretty good? Thanks.
