Most people Nate Diaz from winning the Utlimate Fighter Season 5 and being Nick Diaz's little brother. Nate is a purple belt under cesar gracie jiu jitsu and recently competed against Ryan Hall in a grappling match. Ryan Hall has a crazy BJJ game and is definately one of the elite grapplers out there. His upside down guard is just insane and he can throw a triangle on and finish it from so many ways. I'll definitely be posting more of his video's in the future.
