Mechanics- having perfect breaking mechanics is something that @danaherjohn drilled into our heads from the 1st day he met us. He always said that if and when we get to a position to finish people we should be confident the match is over. Finishing mechanics are one of the most undertaught and poorly taught parts of the sport but are also the most important. The reason you see so many submissions in high level competition isnt because athletes have outstanding finishing mechanics (most of the time they dont) but because most athletes dont practice late escapes when they are already put in bad spots. So they fight as hard as they can to not get put in a submission and then when do get put there they just give up. Here is a video of a beautiful kimura performed by @grouse_armstrong. Dropping from 2 knees to a side control/north south, stepping over the head and positioning herself perfectly along the power line to get a beautiful break at the elbow and actually dislocating the elbow to a point where it stayed out of the socket. For most people this is brutal to watch. But for a true student and scientist of the sport there is nothing more enjoyable than watching a perfectly performed submission.
