Compiling the schedule for this year, I see that Proviso East and Proviso West both have an opening in Week 1. They play each other Week 2 at West. In theory they could fill this hole by just playing each other in Week 1 at East. Obviously there are issues with that, but it could be a solution.
I know that for the last few years, LaSalle-Peru and Ottawa played each other in nonconference, in addition to their later conference game. In the early 2000s, the Four Rivers conference featured five conference games and four nonconference games; all the nonconference games were against other conference teams, so you played four teams twice in the regular season. Does anyone remember this occurring otherwise, at least in the relatively recent past? (I don't mean teams seeing each other in the playoffs again; that's common.)
