They have said that because there really aren't many AA teams, that it would be tough to have a whole season of AA play only and even more travel for the outstate programs that will have AA teams. The one thing I seem to be finding is that some of the associations are going to have AA teams and A teams, not sure if that was the intention or not. Brainerd has said because they don't think they can fill a AA tourney, they won't be having one, I believe they are having a A tournament in both Pee Wees and Bantams though, which would mean they are having A teams at both levels. Blame it on Moorhead for running multeiple a teams the last few year.
I think the intent is to have the AA only really apply for District, Regions and State tourneys. Now District 6 has enough AA teams that they intend to run both AA and A seasons, but that is clearly the exception. I don't know if anyone is planning any AA tourneys. If they happen, they may be in D6.
I think one positive fallout is that it has forced the hands of some mega associations, like Edina, into having both AA and A teams. Essentially two A teams, that they have been reluctant to do. My kid plays in Edina and I have long thought we should have had more teams at higher levels instead of always going for the hardware.
