Leg locks from the heel hook to the dreaded knee bar are some of my favorite types of fight ending submissions. Unfortunately, you don't see them much in MMA or the UFC. Usually because attempting a leg lock submission puts you in a position to take chingasos to the head, cranium, dome! And there aren't too many fighters that want to risk that. On the other hand, there are fighters that feel confident and comfortable enough in their leg lock skills to risk the attempt, even if they do have to take some chingasos to the dome. Check out this video of legend Kazushi Sakuraba in Dream 12 pulling off a knee bar on Zelg Galesic after taking several chingasos to the head an almost being stopped.
