You can't sir BJJ unles you sir BJs first-ever
However some of the best Jiu Jitsu knowledge! I personally can't give second greatest bc of the best Jiu Jitsu by yourself in some basement somewhere. Demian Maia had some early exposure to judo, but it's unclear what. Now this is not to say you can't function too well. If you want to add something outside of UFC like that I'll add guys like Bas.
