Well said, VVP.
I really hate to raise this point, as it may be misinterpreted as a cheap shot at American instructors or the few teaching academies found in America. Still, it has to be asked: Are American instructors getting the job done or have they fallen behind the world in setting and teaching the best possible developmental agendas. Certain aspects of superior play are all about the stroke and basic fundamentals, but other parts of the game are about knowledge and learning how to apply that knowledge to accomplish superior shot conceptualization.
We are in an era where American pros, as a group, are weaker than their European and Asian counterparts in pattern play, defensive play, and kicking, and most of the skills in those portions of the game come down to knowledge and a theoretical comprehension of the subject matter. Are we not teaching these skills at all or just teaching them very poorly? My guess, and it's only a guess, is that we're not teaching them sufficiently.
American players are not doing much to practice the complementary skills. On about ten different occasions, I have asked an established American pro to show me how they practice their kicking. Just one of them was able to do so. Another said he played three-cushion once a week, and I liked that. All the others had no established practice routine for kicking.
For many of the skills, the instructors have to want to teach it and the players have to want to practice it. In far too many cases, that's not what's happening. Throwing financial resources at the problem won't fix things unless we are able to change this.
