Funny, I know Black Belts in BJJ, on this very website and others that do care about lineage.
I personally spent approximately 10 years of sweat, blood and tears earning my black belt and I am not challenging or questioning Jay Russell’s rank or affiliations. I am not sure who you are, nor do I care, but I would recommend you go to Jay’s academy and train with him, or issue a challenge match, to see if you think he is at BB level. I am sure he would be more than happy to accommodate you.
...and this relates to his lineage and BB BJJ claim how? Who said he was unskilled? Who said he wasn't a fighter?
One thing I know for sure is that Jay was accepting challenge matches to prove the effectiveness of Jiu-Jitsu before most people had heard of Jiu-Jitsu or MMA. He has stepped onto the mat, into the cage, and on the street to test his skills.
Also, regarding his relationship with Jordan Damon… they were great friends and training partners. At one point, Jordan was probably one of the best light weights in the country.
Obviously you have some sort of ax to grind; but I would recommend you spend more time training and less time typing.
