I really hate this mindset that there are a finite number of good players and all those players should always play on the same team together. I think this idea very much hampers potential talent and is a great obstacle to development overall. To me it shows an acceptance of the idea that a team cannot be successful unless overflowing with ringers. A big part of the good things about team sports is lost while we look only for the brightest talent at the youngest age. Soccer, as well as all sports, are becoming much less accessible to mostly older players. I don't think that is the right direction. Certainly don't lose the quality and challenge of the Academy and Premier level teams, but let's not assume that those programs contain all the talent either.
If those kids want to join Academy, then let them, but don't force them into that cubbyhole by merger in the name of player development.
