I think the problem found in a lot of arts is looking for things in the art that aren't there.
I was told that a quan sua can stop a double leg takedown; I was also told in Judo that ippon seoinage can be used against the rightcross, and with TKD kicks no one can get close enough to punch or grab you... etc.
Much of it sounds plausible; some of it can be pulled off in the ideal training environment with a compliant opponent. But in reality, not so much.
