If you haven't heard by now, Michigan and Notre Dame will resume their football rivalry soon.
This is an amazing day, and one that should never have happened; for whatever reason, Michigan balked at scheduling Notre Dame in their future schedules past 2014, forcing the rivalry to go on a hiatus. Part of it probably had to do with Notre Dame striking their current deal with the ACC to provide a partial schedule boost in 2013.
But anyway, it's back on, and that's great. College football thrives off of its rivalries, both in and out of conference.
