Too often, people become "hung" on the notion of the action and forget to apply the concept. It should be understood that by attempting to apply "actions" one learns over time how to apply "concept." After that, actions are of no real use other than to teach others.
Combat is a chaotic event. If you're looking for that "picture perfect technique/kodak moment" then get used to dissapointment. However, if you look to applied concept, well then... now you have something to work with.
That's not to say that I eschew jab, cross, uppercut, hook by any means.
Just my two cents.
