To everyone wondering why the match ended when it did (despite the submission being in place), listen to Scott Nelson's interview on the Grapple Arts podcast (it's the Stephen Kesting one) - really good interview, with some rare insight into the Gracie family by a guy (Scott Nelson) who actually lived and trained in Brazil -- according to him, the Gracies were known as bullies in Brazil, and to the common person, having an association to them (or to BJJ in general), was a good way of having doors shut in your face.
Really put some perspective into some of the recent behaviour we've been seeing after Metamoris.
