I dont disagree that he is fast. However, if you werent trying to hurt your opponent, as he obviously wasnt, then you would be faster right? Since you werent trying to deliver any power? Videos like these are gimmicks. He had speed. He had proper technique for a Wing Chun guy, but add resistance and power to it and it looks much different. Just my opinion though. Anyone else?
