he was crossing his ankles when he got hardy's back too and got the hooks in... while it's easy for me to say (as a very low level bjj practitioner), it's another big no-no.
as for the armbar... I can't armbar my son, lachie without pin-point perfect technique. he's hyper-flexible in the shoulder, mildly hyper-extensible in the elbow and can just plain take a lot of pain. I'm pretty sure you'd have to hurt him to muscle an armbar to submission...
