This is a very innovative way to enter into leg control. In the video below Sean Williams demonstrates the technique and shows how to go from a shoulder lock to a foot lock.
The first tekk is the shoulder lock. From the Omoplata what you want to do is triangle your legs and if your opponent tries to stand up you hook their knee with your outside leg while keeping your legs triangled. This is game over. The shoulder lock is super tight.
But on the off chance that you miss the shoulder lock Sean demonstrates how to go from this position to a straight foot lock. Very slick trick to have in your bag in case you miss the omoplata.
