This is a drill that Jason Scully created that is a combination of an armbar drill and an omoplata drill.

This video explains the names behind the rubber guard (why they are called what they are) and a step by step method behind the BASIC rubber guard set up.

There are MANY variations and attack positions but I only cover the basics here: mission control, zombie,new york, chill dog, kung fu move into jiu claw.

There are more advanced attacks and sweeps from anyone of those positions like: invisible collar, asylum, straight jacket, double bagger, reaper, gogoplata, locoplata, Croc, swim move and MANY more.
