No rumblings yet, but this definitely can hit Elgin and friends in a few ways.
Theory #1) Horizon needs a new team. They have the travel partner system setup, which means they'd like an Indiana school to team up with Valpo. Evansville fits this profile and them moving down a tier isn't beyond comprehension.
Theory #2) Not really in play anymore because of Butler, but the A-10 would like a travel buddy to go with St Louis, to bridge to that outpost. Since UIC, Detroit, and Loyola aren't good enough programs to play at A-10 levels, the Valley would've held the other contenders. And with Creighton, Wichita, UNI, Drake, and MSU too far away, and their preference against football schools ruling out the ISUs and SIU, and UE not being A-10 ready, an offer to the remaining MVC team wouldn't have been out of the question.
Theory #3) Maybe the A-10 wants an even more western outpost. Creighton/Wichita is a heckuva package deal.
There's also a doomsday scenario that leaves Elgin no choice but to invite all football members for all sports and causes mass reorganization, but that's a looooooooooooooooooooooongshot.
