The lone logical option at this point might be North Dakota State. The Fargo, N.D., school currently competes in the Summit Conference, is ranked 24th this week and owns a win over Kansas of the Big 12 Conference in September. It plays football in the 18,000-seat Fargo Dome, which would give the league three indoor arenas for football (Northern Arizona and Idaho State being the others).
NDSU would be the 4th as UND is the 3rd.

The men’s basketball team made the NCAA men’s basketball tournament as recently as two years ago. NDSU would make a logical travel partner for the Fighting Sioux in basketball and non-revenue sports and could create a nice rivalry with the two Montana schools. It would also allow Fullerton to realize his concept of divisional play
With USD-SDSU reunited. That leaves NDSU on an island.
