involved at the deepest level.
I'm sure the good'ol eye socket submission/attack dates back the origins of hand-to-hand combat. It seems pretty obvious, given the innate vulnerability of the eyes. We're not permitted to attack them in BJJ or in modern submission grappling. It's probably a good idea to prevent unwanted eye bursting and/or loss. But, these Catch Wrestling guys - they don't follow our rules. They're like wild stallions roaming the plains randomly eyeball submitting and neck cranking people. It's barbaric ... and so we love it.
This is another great lockflow of positions and subs (including an eye submission) from CACC coach, Laren Grey Umphlett. We'd warn you not to try this at home, but that just isn't our style.
