I think the AA, A, B is fine and more than appropriate. The reality is that it is subjective at best when self anointing your own team/club. My son plays for AA and has blown out teams and gotten blown out. I have seen teams that should play AA but play A to get a tournament win. I do think an AA and A is needed. The reality is there are some super good teams out there in fairness that should play in their own bracket for both sportsmanship and to challenge themselves, as there are some very good teams out there playing quality lacrosse but just not "elite" but even that label is subjective.
