I personally find that forcing their knee back in once it is already on the mat is incredibly hard if they have any clue what they are doing. He might have figured out some mechanics I don’t know though…. Or be super strong. Even super strong though, is he gonna roll me back up if I’m driving me knee to the matt WHILE keeping good control of my leg? His opponent did not resist at all in the video and just kind of froze there and waited to lose so I can’t see what mechanics he’s using to get it done if he CAN do it. Beats me, I’d love to learn it if it’s a thing because I’m there all the time and I have to switch attacks and I can tell you some world class leg lockers are switching attacks right there rather than forcing that because I’ve watched them and asked them.
So I’d love to see footage of it live if you’ve got it
