In Colorado, I would probably say Shae Smith and James Strater Smith. Shae's guard is awesome, I used to talk with him about Jiu Jitsu on Facebook before I gave up facebook. Devin Rourke was really good too until he retired, I saw him at Auraria and he told me he gave it up to go to dental school. Seth Daniels got bronze at Pan-Am. Mike Toussignant seems good on his competition record, but from the videos I saw he does not play guard a lot. Also two guys from our academy Josh and Andy. Andy is a brown belt from Princeton BJJ and is really good, with a methodological game. Josh is a black belt and he is one person I can never sweep from guard, I have only done it a few times.
