The point I am making is it’s an debatable argument period. There are outliers on both ends and most are in the middle.
I'll take the 8A middle. You can have the 7A.
Just for grins, let's take a look at it.
Here are the 2019 8A quarterfinals, semis, and final teams and results:
Quarterfinals
Game 25 — Chicago (Brother Rice) 38, Minooka 21
Game 26 — Gurnee (Warren) 18, Bolingbrook 6
Game 27 — Chicago (Marist) 41, Wilmette (Loyola Academy) 27
Game 28 — Frankfort (Lincoln-Way East) 26, Flossmoor (Homewood-F.) 7
Semifinals
Game 29 — Gurnee (Warren) 28, Chicago (Brother Rice) 0
Game 30 — Frankfort (Lincoln-Way East) 24, Chicago (Marist) 7
Championship
Game 31 — Frankfort (Lincoln-Way East) 12, Gurnee (Warren) 0
And here are same teams and results in 7A.
Quarterfinals
Game 25 — Chicago (Mt. Carmel) 24, Chicago (Phillips) 8
Game 26 — Villa Park (Willowbrook) 28, Lake Zurich 10
Game 27 — LaGrange Park (Nazareth Academy) 38, Batavia 24
Game 28 — Rolling Meadows 20, Wheaton (W. Warrenville South) 3
Semifinals
Game 29 — Chicago (Mt. Carmel) 27, Villa Park (Willowbrook) 6
Game 30 — LaGrange Park (Nazareth Academy) 42, Rolling Meadows 14
Championship
Game 31 — Chicago (Mt. Carmel) 37, LaGrange Park (Nazareth Academy) 13
Let's identify your outliers and let's see if we can agree that the top two outliers in each class are the finalists. I propose that the bottom two outliers will be the teams that lost in the quarters to the teams that lost in the semis. If you can agree with the outliers, then here are your middles in each class:
8A
Brother Rice
Marist
Bolingbrook
H-F
7A
Willowbrook
Rolling Meadows
Batavia
Phillips
In 2018, your 8A middles were Marist, Lincoln Way East, Maine South, and Warren while your 7A middles were Batavia, MC, WWS and Simeon.
In 2017, your 8A middles were Marist, Oswego, Maine South and Edwardsville, while your 7A middles were MC, Benet, Lincoln Way West and St. Rita.
I still think 8A smells a tad sweeter.
