I've watched all of his fights. And i know he has a black belt in BJJ, but he rarely uses it. I think it's because of the lack of wrestling. If he was a d1 wrestler he woulda have nice TDD and nice takedowns. Conor pieced him up on the feet, and Nate tried to take him down, but his single, double leg takedowns were shitty. Same for his brother really, just watch how he gets tossed around by GSP.
