no doubt. Though heel hook I don't have a problem with at BB level only.
miller has some criminally underrated bjj though, i felt like the odds of him getting subbed were pretty slim.
his standup looked awesome though!
He tried it against Florian, and one other.
Interesting he posts the arm too. That might or might not be indicative of the Sambo approach to the back scissor sweep, as opposed to the Judo.
I'm not sure how you can do that move without posting your arm. Seems you'd just hit your face on the ground?
Although I know someone who did this and posted wrong, and hurt their shoulder really badly. So you definitely don't want to put too much weight on that post.
