Since this is a quick demonstration, I’ll break down the principles a bit.
Before any scissor sweep can occur, you must damage the structure of an opponent’s position. Generally, that’s done by loading the person’s weight forward. That brings their hips off of their heels and creates a lightness in the lower body.
But, one thing that can always be counted on is resistance.
Opponents will widen their base or sit back more, and that’s where the kick out comes in. It’s another way (and perhaps a better way against larger opponents) to run roughshod over structure and sweep to mount.
The resistance doesn’t stop there though.
Sometimes, people also base out on their foot. And when that happens, it creates an opportunity, because they have shifted their base to one quadrant and left a massive hole behind. Towards the direction where the foot is planted, their base is strong, but that’s not so true the other fact.
In fact, it’s easy to off balance them in that direction. And that leaves them with a choice. They either base out on the hand or they get swept. Either you win, because if they base, your grip is already in the collar.
And now their posture makes the transition to the loop choke almost effortless (if you’ve spent time working on its execution).
