You put no conditions on it, save schools that we chose not to play. One might think it's safe to assume that we choose not to play a team from the lower three divisions. As such, the answer would seem to address the question directly. You don't like the answer? Ask a better question.
Just out of curiosity, what division is Glenville in?
You might also note that Moeller played at Ironton a couple of years ago. It weren't no blowout. Maybe some of those lower division teams aren't as far below us as you think. After all, we did just lose to Big Walnut. That sure as hell doesn't scream "Superpower!" to anyone.
Teams that called us? So, it's no longer incumbent upon us to fill our schedule; we leave that to other schools to initiate contact? Then WTF does the athletic department do in the off-season? Let's make this easy: there were 192 playoff teams in the upper three divisions. If we call them all, that breaks down to about three calls a day from the end of the season through February. Is that too strenuous of a workload?
C'mon dude. You're close to the program (

). How about you give us the list of Ohio teams we called about filling our open dates? Then give us the reason that each of those entreaties did not result in a game. I predict crickets...
