My short answer is, the better fighter wins, the one who knows what he is doing, wins. And that is regardless of what style or school he is trained in.
Wing Chun is no doubt an excellent method of fighting; and so is boxing, if the fighter is skilled at it.
And, that is my answer, the skilled fighter and the one with the most heart, will win.
Note: How many excellent fighters have been taken out, by some creep ambushing them?
I suspect that there have been a few. A good fighter remains ready to go, and I think that some people forget that.
The man that made the video, seems like someone who could fight his way out of a bad situation.
The issue you may get there is if you focus on undefinable results. it removes the importance of getting the definable parts of your training correct.
So yes a trained fighter could get jumped and bashed. But how do you train to defend that in a way where the results are predictable?
Does that mean that punching kicking grappling is less important?
