If any of you are watching the latest installment of The Ultimate Fighter, a fighter who started with our little group here is on the show, Bristol Marunde: http://www.theultimatefighter.com/fighters/bristol-marunde
He started here while he was in college, and eventually went to train full time with Xtreme Couture. Apparently, he trains with Forrest Griffin a lot. He has some decent experience, with a fight take on short notice, in Strikeforce against Jacare. Loss, but a pretty decent showing.
He has good standup, but you can tell from his first fight that his base is wrestling, with solid BJJ (which is the emphasis around here.) The guillotine was tight, technically sound (especially in positioning, which guys who learn at subpar schools often get wrong) and the result was a nearly immediate tap. Incidentally, unless you have a great squeeze, or are just that long, the guillotine from the closed guard is pretty easy to fight out of. You just post your head, lift up your body to relieve pressure and to force the guy to use a lot of core to keep the guard tight, against gravity, and push on the elbow. All working with gravity. If you see the way Bristol did it last night, his angle prevented his opponent from this rudimentary defense. If you watch a high level guy like Nate Diaz, he will often throw his leg over the shoulder for extra leverage and to prevent the opponent from squaring up the shoulders and initiating the shake and bake defense.
Also, he is huge at Welterweight. He usually fights at 185 lbs, and a lot more musclebound.
Incidentally, seeing him overpowered for part of the round against the fence reminds me of how strong and well conditioned are MMA fighters compared to how it was when I fought (back in 2000-2002).
