^ valid option made possible because he can't roll. This is a huge benefit to this position/sub. Just like the ic will tap some, but control the shit out of all. He's pretty stuck. He can still push the foot over his head and escape. Hard but doable.
That's why I thread over my foot and under his armpit and s grip around his shoulder. The straight jacket can be a huge battle too, and I like to wear them our in this grip first. Plus it eliminates the duck out.
