There has been so much hand-wringing, so many theories for strengthening the Summit...
Would really like to see the formation of a Great Northern Conference - add the Montanas, Idaho, EWU. Probably a long shot to get them to leave the Big Sky.
Doubt the MVC will be willing to give up control of the MVFC to the Summit, even though they share offices, iirc. A nice idea though, if you could pull it off.
Get the MVC to add the Dakota 4. Their recent solution of adding Valpo suggests that will not happen.
IMHO, it seems that the fastest way to 'fix' this is by <choke> getting the old band back together. Entice Northern Colorado to leave the Big Sky and reunite the former NCC schools who have moved to D-I under the Summit banner. It will give the Summit 6 football teams, add a basketball team that has made a March Madness appearance and adds a baseball team (which wouldn't be as important if the Summit were to break off into their own football conference), but no men's soccer.
For soccer, the answer is probably to add UMKC.
The addition of UNC and UMKC would bring the Summit back to 10 after IPFW bolts next year and gives the Summit the baseball and soccer teams it needs. Plus it would make the option of Summit football possible with the Dakota 4, Western Illinos and Northern Colorado. Then add Minnesota State and/or Minnesota Dukuth as a move-up for insurance for WIU and Oral Roberts.
Don't like this idea as much as just staying put in the Big Sky, but afraid that ship has sailed and UND's move to the Summit is inevitable.
