UMKC does nothing for the Summt's compliance with Division I membership criteria. Since the Summit doesn't sponsor football, it needs six schools who play men's soccer and baseball. Up to two affiliates may be used to satisfy one of the requirements.

Men's Soccer:
Omaha, Denver, Oral Roberts, Fort Wayne, Western Illinois, Eastern Illinois (affiliate)

Baseball:
Omaha, Oral Roberts, Fort Wayne, Western Illinois, North Dakota State, South Dakota State

The Summit losing Fort Wayne would be very costly. Even if the Summit were to add Eastern Illinois as a full member, it would still need a soccer affiliate like Central Arkansas.

Of course the Summit could quit sponsoring men's soccer if it added Eastern Illinois or Northern Colorado, but it would have to split from or takeover the MVFC, which may not sit well with the MVC schools.

UMKC adding baseball is the only way they get back in the Summit, as they become a straight up replacement for Fort Wayne.
