FCS Rankings You'd probably need a scenario where two of the Dakota's win out, giving a couple losses to the others, and we would have to lose tight games to the Montana schools while handling Northern Colorado and Sac relatively easily.
NDSt only plays South Dakota and they have 3 ranked wins. Losing that one puts them at 10-2 so they'd be ahead of 9-3 UCD regardless.
Montana State would also likely be ahead of us since in that scenario they'd beat us and, at worst, have the same 9-3 record.
The other Dakota's come down to how the games go. You could have a scenario where SD beats NDSt but loses to ND and SDST. Then you'd have NDST with 2 losses, SD with 3 losses, the winner of SDST-ND would have 2 losses and the loser would have 3 losses. All four would probably be ahead of us.
If Montana beats Montana St and UCD, they'll likely win out, would be 10-2 and ahead of us. Even if they lose to MSU, a 9-3 Montana with a H2H win over a 9-3 UCD is probably ranked above UCD.
So realistically, we'd have to finish 10-2 to be in the top-3 or 4 unless some upsets happen.
