It sounds like it's a go for NDSU. I wonder who the other two will be and what a timetable is. Also, would they hold out on an invite to the Mid Con for this deal?
As a UND alum, the news release from this past December that UND had officially assembled a DI review team was a clear signal that a DI move is practically inevitable. The very action of publicly announcing a DI review team destabilizes the seven-member North Central Conference, which UND has previously vigorously defended. UND has informally studied DI for years, but its leadership has practically insisted that a DI conference bid be at a minimum informally forthcoming prior to moving up. IMO, the Big Sky must have given UND a clear signal that they will be invited. Watch for a DI announcement by UND in May. This fall, watch for an announcement by the Big Sky of another round of expansion. IMO, a 12-member Big Sky conference will be in place by the 2008-9 season after adding SDSU, NDSU, and UND.
As for the NCC, I think UN-Omaha will leave and join the MIAA. UN-Kearney will also leave the RMAC for the MIAA.
The remaining five NCC schools will have to try to piece together a decent DII conference. Winona St from the NSIC, Wisc-Parkside from the GVLC, and Mich Tech and N Mich from the GLIAC would probably be the targets. The NCC may morph from a northern plains conference into a northern woods/lakes conference.
