I agree with that but how can you know how they handle that from a video and why are you so convinced that their structure would fall apart? Maybe a crystal ball or something?
The center line tactile game?
WTF is that? If you mean by driving up the middle and looking for arm contact then I agree but that's not how Ving Tsun works. Only in systems that have got it wrong. Going up the middle is dangerous unless the other guy has his arms down and looking for arm contact is a useless idea.
In reality? You mean street fighting?
I don't think your idea of Ving Tsun is correct Frost and that's maybe why your POV has been distorted.
