Last year, the Big Ten Conference announced a football strength of schedule commitment. At that time, the conference stipulated that its members must play at least one non-conference game against an opponent from a Power Five conference or BYU or Notre Dame.
In addition, the Big Ten agreed to discontinue the scheduling of FCS teams with the exception of those that had already been contracted. . . . Here's link:
