Standing, collar grip
Drop to Double Leg
The backup for the collar drop. When they post and stay on their feet as you sit, come up to your knees, wrap both legs and drive them down.
Step by step
Start the collar drop
Collar grip, step deep between their feet and sit down, pulling on the collar.
They stay standing
If they post a hand and keep their feet instead of tumbling over, don't stay sitting under them.
Come up to your knees
Turn toward their legs and come up onto both knees, head tight against their hip.
Wrap both legs
Let go of the collar and wrap both arms behind their knees.
Drive them down
Pull their knees in to your chest and drive forward with your shoulder so they sit down onto the mat. Follow them down on top.
