I'm not taking issue with your proposal, but I do have a couple of questions. How do you resolve these situations:
1. OK, so you've got 6 teams in the district. Team A beats Team B; B beats C and C beats A. A, B and C all beat all the other teams in the district and all three teams finish 4-1 in district play. Classic three-team tie for the district title. How do you break the tie and determine the District Champ who then goes into the playoffs while the other two teams stay home? A three-team playoff (one quarter each)? When does this playoff get played - the Monday before the playoffs are supposed to start?
2. If there are only 3 districts in each region, how do you set up the regional playoffs? Does one of the three teams get a bye? If so, how do you determine which team?
3. Let's say District 1 has two really, really good teams and District 2 has six crappy teams. Are you OK with the District 2 Champion going to the playoffs while the District 1 runner-up stays home because they happened to lose a close game to the eventual District 1 champion early in the season on a questionable call?
Personally, I like the idea of 6 teams in a district. But, I'd stick with 4 districts in each region. If that means reducing the number of classes, so be it. The 4 district champs (using whatever formula or playoff system works best to determine the district champ in the event of ties) host the first round of the playoffs. I don't care if everyone in the world knows that a runner-up from one district is better than the champion of another district -- if you win your district, you deserve to host at least one playoff game. Period. The top remaining four teams fill out the field of 8 teams in each region. I'll leave for another time the discussion of how those remaining four (non-district champ) teams are selected, but it would likely be through some sort of power ranking. Same system would determine the seeding of the top 4 district champs. Yeah, I know this system looks a little familiar, but assuming you have a decent power-ranking formula, it should work.
Love for SSAA. Two great matchups that could go either way and should be one-score games.
