Interesting, I have had 0 encounters with the Japanese Jujitsu perspective knowingly, the timing of when it is he should have rolled forwards makes a lot of sense, I'm certain i've seen this kind of escape now that you've mentioned it, but can't think were.
And watching the other leg is fascinating, both really, watching it over and over in this format you can really see how technical it is from that perspective.
I'd be interested to see if there's any push back or additions on your breakdown because it's genuinely one of the best i've seen on something like this. Hat's off to you.
If I wasn't already hoping fo more leg locks in MMA, I really am now.
