sorry for the long winded setup, but i dont care about your time. I have 2 instructors, 1 a black belt who is old school bjj and 1 a brown belt who is more mixed grappling styles. The brown belt taught the black belt up to a point and owns the school. ANYWAY, he was delving into uncharted waters (for my school, anyway) today with leg locks. The black belt aschews leg locks and wont even teach them to anyone below a brown belt (though he rolls to a knee bar fairly often). I have 3 years with a sambo instructor under darren pordash and gokor who was a bit of a leg locks genius. i gave them up because when i came to my bjj school i just got my ass handed to me by the more tradtional bjj guys. and i just wanted to focus on mastering positioning. so i am more of the school that believes leg locks hinder progress my brown belt instructor started us on a system today. Scott Sonnen has developed a leg lock system that he claims is more or less fit for bjj comp. That is, the main complaint about leg locks in bjj is that you have to give up a position to go for one. and when you dont get it, which is a fairly high percentage of the time, you end up screwed. I mostly agreed. The system basically stated that there are 4 leg lock positions (sort of like mount, side, guard, and rear mount), and that by using these positions you can go for leg locks and not give up position, you can transition back into traditional bjj positions without "bailing out". The homo-erotic names: full saddle, side saddle, half saddle, rear saddle. I only learned full, side and half today. I have to say they really do give you alot more control over your opponent than traditional leg lock setups. I landed full saddle, which is essentially and figure4 with the foot tucked in the crotch and the outside knee on the mat, on a purple belt today. And although i didnt finish the ankle lock, i held him there for at least 2 or 3 minutes with not much effort. the main thing is it didnt feel like i was just playing footsie and bailing out. anyway, anyone have any familiarity with sonnen and these leg lock postions?
