They wanted to join the Summit and MVFC all along.
Summit was resistant 5 years ago, due to the NCAA legal fighting over the FIGHTING SIOUX nickname.
So the Big Sky invited Southern Utah, South Dakota, and North Dakota, and all of a sudden the Summit and MVFC swooped in and also invited South Dakota only.
South Dakota took the Summit / MVFC invitation, and the Big Sky was sort of stuck with North Dakota.
So the MVFC is sitting at 10 teams - pretty sure they play a 9-game round-robin.
Summit could easily add North Dakota - they're a perfect fit, if all the animosity over the Fighting Sioux pissing contest is over with.
Proceedurally, North Dakota will want to have invites from both the Summit and the MVFC in hand, before they submit any paperwork to exit the Big Sky.
That's where they are now.
They may need to do a selling job to some of the eastern members of the MVFC, who aren't as enamored with travelling out to the Dakotas.
North Dakota would be the 11th team in the MVFC. I wonder if there is a 12th team (like perhaps Wichita State starting up FCS football),
that might support allow the MVFC to split into 6 team divisions East and West ?
It might be possible, if that 12th school comes along with North Dakota.
