That's kind of my thought on this. It's not like CG ran away from or gamed the system. On the other side of the coin, folks would be flipping their wigs if, to avoid having to find stout out-of-state competition, CG loaded their schedule with a bunch of in-state 2A/3A schools with an open week of play and maybe a promise of the gates. That doesn't help anyone.
If that's going to be a rule, then the IHSAA needs to step in, decommission all of the current conferences, and go to districts with assigned membership. I'm sure that'll go over like a lead balloon.
