Couple of random thoughts, First KM is now trying to keep out "outside techniques" so people don't keep adding and calling it KM? That's just proprietary BS, Imi's KM when he founded it looks not a whole lot like what is called KM now because of adding techniques. That was kind of the whole point of KM is that if it works and is effective and fits with the criteria than it IS krav maga. This is someone just trying to sell their version and controlling others. Second, I keep seeing people talking about seeing things in their peripheral vision in a self-defense situation. Always a red flag for me unless there is further explanation because once the adrenaline hits that is the first to go. It is why people get hit with shots that looked telegraphed to a bystander but the person never saw it coming from that angle. Lastly, I think this is one of those defenses that is great against an untrained person just throwing punches in a haphazard headhunting manner like many streetfights. I don't see this as effective on someone who can keep range and change up the angles of the punches and targets. it leaves the body wide open (which is also one of the complaints on the Crazy Monkey Defense). Again, videos aren't always clear but I keep thinking about an uppercut right up the middle and you wouldn't see it coming.
