A Wing Chun instructor, -anywhere in the world, could release a video about "anti-grappling" and make a fortune, if it showed realistic takedown defenses against an average collegiate wrestler, and realistic sub-defenses against an average BJJ purple belt.
The fact that there are so many WC people in the world (thus an obvious demand for this type of video), makes you wonder why this hasn't been produced
I don't think Wing Chun is so limited that I can't do it when I wrestle, box, kickbox, or fight by MMA rules, nor am I so limited a student that I can't improve by training in each of those forums. -Andrew S
A good instructor encourages his students to question things, think for themselves and determine their own solutions to problems. They give advice, rather than acting as a vehicle for the transmission of dogma.
