We actually do have some vids of us (his students) sparring with him. The problem is that he is so much better than we that we all look like clumsy amateurs when facing him, so I don't think the vids look very convincing.
He's also had a few fights against boxers, sanda guys, and MMA pros (or is it semi-pros?), but there aren't any videos. Anyway, those were mostly closed-door so it would not be right to post them even if we had them.
