Appears as the guy had turned his arm back to defend early on(so it comes back around the leg). So later when the armbars were actually being applied there was nothing for it to be applied to as the arms were turned the opposite direction.
I love that video "Tight like a mans ANIS"
Orlando Hotbox VP Dartangan "The Sorcerer" Jackson has posted the vid here on the forum and catches guys in practice all the time. He was the first ; )
Yea I'm the guy from Florida that almost pulled it off. Eddie told me that I needed to sit up and hug my knee tighter and I would have got him. the guy did not like being in it at all.
