Still on this:
6A only: Crown Point, Lake Central, Portage (DAC); Elkhart, Penn (NIC); Carroll, Homestead, Northrop (SAC), with the interloper being the Bengal (or Fighting) Tigers of Warsaw (NLC, but they need love, too).
A little more creativity to bring it to 16 would ensue adding Merrillville and Valparaiso from the DAC, Dwenger and Snider from the SAC, and since I don't consider anyone else worthy from the NIC, I'd advocate for Huntington North, Munster, and Plymouth to make it even. Championship game at Notre Dame Stadium as I'm sure they wouldn't mind...
Let the games begin.
