Good detail to point out to people. That stagger step is also absolutely critical to ankle picking or cross-ankle picking anyone decent off collar ties (or lapels) too. Once i figured that out it had similar experience with those.
Couple of my students competed this weekend and were working on gripping up and snapping down with what we call "folding the laundry" like you're shaking out a towel you just took from the washing machine. Powerful move!
As a BJJ guy who knows jack shit about wrestling I thought of you when I saw this clip. Henry Cejudo shows a very classical shot here. But at 4:00, he shows the idea of covering distance by stepping forward with your back leg first. While this is certainly an idea I've used a lot in judo, I've shockingly never taken a shot this way. Hope you like it!
