To the divisions talk…. I think the way they should do it re-organize leagues so that there are D1 leagues, D2 leagues, and so on, all the way to D7. League winners are obviously in, most likely with first-round byes and home games. 2nd place teams get in, but travel, etc.
Since leagues are all one division, everyone knows their playoff target BEFORE the season starts. No need for selection committees, except maybe to determine and seed Open.
This is roughly what was going on when I moved to Oregon, but it was better when they had just four divisions among their 500 or so schools. One big difference was no Open division, not needed.
It became more diluted when they went to six divisions…. Just not enough schools per division. But I think ya get my drift…
