I think if the SIAC couldve added Gibson Southern and boonville in the expansion, the football schedule would've benefitted from an east/west division instead of big small.
West-MD, Reitz, Central, Lincoln, Gibson Southern, North
East- Castle, Memorial, Jasper, Boonville, Bosse, Harrison
5 games in your division, 2 rotating crossover games, 1 out of conference game, 1 championship week. I'm not convinced the championship week is necessary, and without it, the schools could schedule two out of conference games.
