Just change the way and number of teams that go to the State Tournament.
Basketball should be the same as football. Take the top 2 from the district tournament (no matter how many are in the district), play a sub-region game (higher seeds host) and then take the 4 winners in a region (each region would have 4 districts in it since there are 16 districts across the state) to Region tournament. Winner of the region tournament advances to State. State would be the Final Four from 6 classes of schools.
The whole reason there are 4 classes is because for years you had schools in classifications playing people with 2xs the enrollment. They tried to fix it and it would have been fixed had they gone to 5 classes instead of mamby-pambying around and going to 4.
Alabama state tournament has the blueprint but T$$AA aint looking for the good of the kids- just their pocketbook.
