So here’s something you don’t see everyday, rubber guard from side control leading to a submission, for the guy that’s in side control.
We see in this video that Marcelo Garcia gets the sweep, passes quarter guard and starts to settle into side control when the guy in the blue shirt quickly attains rubber guard from bottom side control, and proceeds to sweep and choke with basically an inverted triangle. It looks like you need a certain level of flexibility and comfort with being stacked on the bottom to pull this off. Gonna have to try this in class this week.
