We already know IU will be a protected rivalry but we also get 2 other "regional" rivalries that won't be home-and-home every year but it sounds like we will play them twice in 4 out of 6 years. I would guess that for us it will be Illinois and Northwestern.

As for the schedule changes coming next year, regional rivalries will be protected. There are three in-state series that will be guaranteed home-and-homes: Illinois and Northwestern, Indiana and Purdue, and Michigan and Michigan State will always play twice.
"Under the new men's format, teams will play seven opponents twice and six teams once (three home, three away) in a given season," the Big Ten's press release says. "The new schedule will also include a regional component to increase the frequency of games among teams in similar areas. Over the course of a six-year cycle (12 playing opportunities), in-state rivals will play each other 12 times, regional opponents will play 10 times, and all other teams will play nine times."
