Top 4 seem pretty cut and dry, next 4 seem cut and dry, as well. The Southern most 8 are the issue, yeah?
Aren't Plainfield (congrats T Bless), Franklin, DC, and Whiteland in the same conference?
But even those 4... anyway you cut it--- FC/NA/Sey/CE + BN/BS/Castle/EN-- this would be the most traditional route, then obviously BN/BS/CE/Sey + FC/NA/EN/Castle would be the other option-- are all pretty simple options and drives.
I assume they will keep the HHC teams together. SEY, CE, NA, and FC.
