Really, what I think is that they had not "properly" trained for the event or for "real contact". I my time, I have seen enough schools whose predominant focus is form (kata) and not application and sparring. I was young when I swtiched off from gung fu to Uechi, the primary reason being what you see in that tournament. I never regreted the decision, having sparred with some apparently talented gung fu guys (including one who is now a famous action star.)
Notice the wing chun guy. Yes, a flurry of punches to the Japanese guy's midsection but to no effect. His own physical conditioning was lacking (Yes, he was also flabby around the mid section) and was dropped by one or two midsection punch by the Japanese fighter.
Fighting that kind of tournament, one would have to work on endurance, power and conditioning in addition to the the skills/attributes related to the "give and take". I just didn't see that reflected by gung fu guys. In the interest of being fair, the tape didn't follow their training as much as some of the other fighters.
That's why I think the tape is interesting. Ponder your training.
P.S. Oops, my last comment was not directed at you, Anthony, specifically. Rather, towards "we" who may be interested in this facet of training.
