I will, but in the mean time, here's a single leg wrap, as opposed to a double leg wrap, and no, it isn't the same as a single leg takedown. Wrapping the leg up in your arm while grabbing the torso. You do not directly grab the leg, and this causes for a much tighter technique, if you can get it. If you're going to tell me it's basically a single leg, consider this: Why is Mounting/Guarding in T4 while Pulling Guard is in the BJJ tier?
