Is the kneebar applicable in MMA?
I'm curious as to what everyone thinks. Is the kneebar a viable submission in a MMA match, or does it leave the back of your head too exposed to strikes? To be clear, I'm not talking about the headlock-grip kneebar, but the more traditional move wherein you're hugging the foot to your chest with both arms.
I know Shamrock and a few others pulled it off, but nowadays people are more familar with leglocks, and are less likely to be caught off guard by them.
So what do you think? Will the back of your head get caved in (assuming hand strikes to the back of the head are allowed) or can you finish the sub beforehand?
