Jin Young and Wing Chun Blast

That was one fighter going to one seminar. Doesn't mean he does much training in that method.

My understanding is that a number of MMA guys who train with Ray Burns also train with MM. I've no idea how often they train with him, but their comments show that they see him as the real deal and think his art and training methods are to be taken seriously.

Jumping rope is a side conditioning device that supplements the major boxing training that resembles the way the real fighting is performed.

There would be no problem with chi sao if it was also just a side conditioning device to the major training that mimicked real fighting. That doesn't seem to be the case though.

Well, it is true that I wouldn't call CS a 'side conditioning device', as it is given quite a heavy focus within training, but it is a device.

Wing Tsun is forms, bag work, Chi Sau, Lat Sau, sparring, strength training. Chi Sau is one part of the puzzle.
