Here's an idea of how the playoffs would've looked in 2023 (granted this is a ballpark guesstimate because records would be very different with expanded conferences and new matchups):Alright, I think after reading it about 38 times, I've figured out what you mean by how they do things, so I'll work on conferences for that later.
What I'd do with the current setup of the top 36 teams in Class 5A is consolidate it to just 4 conferences making up the largest schools.
-16 teams make the playoffs
-top 3 from each conference are guaranteed a spot
-remaining 4 spots are at-large berths
-top 2 seeds host 1st Rd games
-Regular season is 8 conference games, and 1 non-con
Here's how I'd divide 5A:
Central Iowa Metro League-
Ankeny
Ankeny Centennial
Johnston
Urbandale
Southeast Polk
West Des Moines, Dowling
West Des Moines, Valley
Waukee
Waukee Northwest
Iowa Crossroads Conference- (because every school is connected by the major roads HWY-20 and I-35)
Ames
Des Moines North*
Des Moines East
Des Moines Lincoln
Des Moines Roosevelt
Sioux City East
Sioux City North
Cedar Falls
Waterloo West **
Mississippi Athletic Conference-
Bettendorf
Davenport Central
Davenport North
Davenport West
Dubuque Hempstead
Dubuque Senior
Pleasant Valley
Muscatine
Ottumwa
Mississippi Valley Conference-
Marshalltown
Linn-Mar
Cedar Rapids Jefferson
Cedar Rapids Kennedy
Cedar Rapids Prairie
Cedar Rapids Washington
Iowa City High
Iowa City Liberty
Iowa City West
*-an exemption would be made for Council Bluffs Abraham Lincoln, so that they can stay paired with more of the teams in their region, and not be a complete geographical outlier in 5A. DSM North currently has a total BEDS over 1,000 and given their natural fit with the other metro schools, that is why they replace CBAL
**- Waterloo East and West will be merging into one centrally-located HS, expecting to start in 2028, which will make it one of, if not THE largest school districts in the state.
