Marcelo Garcia is a huge name in Brazilian jujitsu and grappling. Nick Diaz was known for his BJJ and a black belt under Caesar Gracie and Karo Parisyan is a solid world class judoka who was an alternate in 2004 judo Olympics. Also Josh Koscheck was an NCAA wrestler and one of the best in the country. Yet Diego was able to grapple with them evenly and held his own and showed that he was on their level. I just don't understand how he would get submitted by a guy like Fabia in 40 seconds!?
