You are living in a fantasy land if you think the DA is going to radically change things.
Around 2-3% of the girls in the DA will ever get called into an actual USYNT camp. So the rest of the girls (and their parents) are going to measure the success of their development on what? Pass connection percentage? Strings of passes? Possession %? Juggling achievements? It will not be how they play against outside competition, since they are prohibited from doing so. They will measure it based on performance in the DA, the only measure they have. A losing DA team that is sending 1 girl to regional camp every year, and is maybe getting one (1) girl on the actual YNT every few years, is going to be viewed as a success and be a huge draw? Not likely, since US Soccer is awarding DA status to so many clubs. Winning will be important (they keep standings and hold championships at the end of the season), and coaches will do what it takes to win, even in the DA.
I agree, US Soccer should focus on coach education and improvement, a path they started down with
Claudio Reyna's curriculum and standards, which unfortunately where put on the shelf in 2011 only weeks after they were released, as Klinsmann was hired and assumed the technical director role as well. I still think that was a better path and strategy to start with than DA. It needs to come first in order to make the DA actually have the impact everyone wants.
