St. Xavier (Cincinnati) at Colerain (Cincinnati)
When: 9/6, 7 p.m.

Now, the teams are in very different places. Colerain went 14-1 last year and played in the championship game; St. Xavier finished 5-6. But even that regular-season matchup was brutal, with Colerain eking out a 14-12 win. This rivalry is as good as it gets.
