It's a hard subject to broach through words alone. God knows I've tried! It's become somewhat obvious to me, with all the different "ideas" of WC floating around this forum, that a certain foundation is required to even grasp some of the concepts I try to express, the biggest being understanding on how the body, legs, abdomen, arms, are even interconnected. People, by nature, get tunnel vision and often don't ask why something is the way it is. Often people find something that works and focus on that. Often times that "thing" is a what I call a WC "trick". A manipulation founded in a knowledge or weakness, often predictable, in the practitioners system that they exploit. This doesn't make it true and more times than not becomes a "self-fulfilling prophecy" and added to the system as a result.
It is human nature to want to maximize ones potential in any given subject. The problem isn't in the desire but in the short cuts to get there quicker. How many here do you think actually work on the foundation? How many here do you think get bored following the principles because they can't make them work when they want them to? How many people do you think understand what is developmental(99% of the system) and application(1%, just the structure and the punch in all its forms)? The theory of WC is flawless. The principles are sound. The concepts are solid. But why is it so hard for people to make it work?
I offer a few things to think about.
Yes, your comment about TST is not too far off. The structural framework is a rotation of forces much more along the lines of a circle or spiral within the context of a triangle "base". There are MANY things going on there and the term 'go with the flow' is an understatement. Think of a balloon floating freely against a movable wall. The wall being your body as a whole. The balloon being your arms and abdomen. If you press dead center on that balloon surely it will compress and if the wall is dead center behind that ballon surely it will move back.
What good WC structure does is take this concept to another level. What happens when that balloon isn't pressed center? It rolls with the compression. What comes forward despite the compression? The balloon. What happens if the balloon is pressed off center but the wall rotates forward to the side of the force? It rolls while staying hinged to the wall due to opposing forces. i.e. facing. What comes forward towards the thing pressing it? The balloon.
This concept, in combination, is WC structure in motion. The post I made earlier about the spiraling you'll notice of the elbow, if done correctly, along with the ability to switch between active and passive facilitates this concept in the place of the balloon. The "bracing" footwork along with distance facilitates the place of the wall. The force coming in quite literally is showing you where to hit when your path is obstructed and naturally creates a structure where your body is balanced allowing you to deliver force to your structural limit.
This "positioning" is not made intentionally but is a response through adjustment. This positioning is the result of foundational work drilled over and over and over again.....and a good teacher.
Now I don't want anyone to think WC is as simple as that. It's not. There's many other elements involved such as asking hands, timing, kicks, footwork to and fro, multiple opponent footwork, etc. It's a complete system. But the core structure, the reason EVERYTHING else exists and why, is based upon allowing this structural concept to exist...
