Thank you for sharing this on the forum. It's a great video and I always enjoy hearing Eddie speak.
Rigan also preaches this exact setup when playing from the half guard position while having the outside leg [butterfly] hooked in between the opponent's legs. The method that Rigan taught changed my bottom game forever. He also credits both Jean Jacque and Eddie for a lot of what he teaches in No Gi. Rigan has some interesting Twister variations that are so damn cool!
