No offense intended to Bas Rutten and I am not suggesting that he isn't credible, but I find it interesting that this video has been posted in a Wing Chun forum for a full day and none of the usual voices of discontent have any issues with the compliant attacker.
A Wing Chun video making similar claims (or not) that featured this level of acting and cooperation would have been ripped to shreds by now.
Of course! Wing Chun = bad. Bas Rutten = good.
Seriously though, I'm not being serious.
