In all seriousness, if everyone really wants to find a way to limit the number of p/p championships, I have a radical suggestion, limit the size of public high schools. Indiana has absurdly large public schools, and there is no good reason for it. This is a small state. The fact we have six classes of football is absurd.
Ohio has double our population, but only one high school larger than 3k and only five large than 2500. Indiana has 19 schools larger than 2500. Schools that large cannot serve their population well. Cap public enrollment at 2500 and change football to four classes. Most of the p/p's have 500-1500 in enrollment, so they would almost exclusively end up in 2A and 3A, knocking each other out.
Carmel, sorry, your three new high schools will knock each other out in sectionals.
