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?
I do agree if hr added more power, he'd lose some of the speed. I also noticed that hes attacking to the neck area, and my general thought on power is "How much do you need when striking the neck?"
