Ehh.. I have always suggested that clubs be allowed only 1 AA team per level, and must have an A team as well. I also support simply letting AAA/AA/A tryouts go for two weeks and they all start at the same time. I feel this would achieve the same results w/o all the "oversight and hand wringing" and $$$ spent on Labor Day to draw lines during preseason. There was a time we did AAA/AA/A tryouts at once, but the clubs could not capture or hoard players as easily. Kids landed more or less where they belonged.
I am also somewhat lazy, so if you can achieve the desired results w/o all the "work", and with a couple of simple rules anyone can follow. Im in.
Having AAA/AA/A tryouts all at once gets teams sorted pretty quickly - since its like musical chairs, where there are more players the avails spots when done this way.
