Best defense for a collar grab from a standing position as a pure grappler

[rmongler]

I could swear that I saw a video where he wizzered the underhook and grabbed his hads together and he torqued like crazy. I think it was in a gi match actually

Aoki had that 'instinct for doing damage', so it would not surprise me if there were even more examples of stuff he's done out there.

Ippon Seo Nagi is the answer to your query.

Einarr would approve.
