I wanted to make clear that I wasn't suggesting that there be any limitations on the club for which any particular player can play. It ought to be up to the kids and their parents to determine which place is the best fit for them. Rather, I would like to prohibit solicitations from clubs to players beyond written notice of tryouts.
If a "super-club" develops (which it won't) well, so be it. What isn't ok in my book is the practice of affirmatively seeking out players from other clubs and enticing them to leave.
