I love the dvd set to start, but I just have some questions for people who have watched it but maybe can either identify a bit that I missed or have worked in out how to apply his concepts in positions he doesn't address. Firstly, what do you do if someone passes to knee on belly instead of coming straight to side control or leg drag? They're outside of your arm defense layer range but inside of your legs and knees, does this negate the system of concepts or is there a layer I'm missing here? Secondly, in what I've come to think of as a hierarchy of defense layers, some guards fit into a specific place in terms of distance management of specific pass defense. Certain passes call for a specific layer of defense because they assume they've passed certain layers already I. E. If someone leg drags to the leg drag position, you sit up and depending on distance either go straight arm or collar tie. Someone knee slides and depending on the stage of the pass you can either rdlr or knee shield to stop it, followed by the arm centric layers of defense if they get passed those layers first. Where in the layers of defense would you put single leg x and x guard? Which wall level do these fit into and do you have examples? Thanks in advance.
