"In New York, the cause of death of the jiu-jítsu fighter Rockson Gracie was announced. The findings of the autopsy disclosed that the 19 year-old Brazilian died of an overdose of drugs and medicines."
Rickson has 3 other children alive and well so I'm not sure if there was a secret 5 child that died at the age of 9, but he definitely stopped fighting after Rockson died, thats why he never fought Sakuraba.
I know how notorious they are in Brazil, I know the Gracie story, I've read articles and books and have trained with people who train under the Gracies(Renzo)
What I'm saying is your facts are flawed.
They don't post things about him because he doesn't want people knowing everything, because then the Myth that is Rickson Gracie can live on.
I'm not discrediting him he is a great Jiu Jitsu practioner, one of the best, but going back to what the postings were about in the beginning...he isn't the best fighter in the world.
