Montana, Montana State opt out of spring FCS championship season Also with Southern Utah heading to the WAC in 2022 that will leave the Big Sky with 12 football playing members. I think there is a good chance the Big Sky goes to two six team divisions. Each team plays the 5 teams from their division and 3 from the other division.
My guess at Divisions:
North: EWU, PSU, UM, MSU, UI and ISU
South: UCD, CP, Sac, NAU, WSU and UNC
Another possibility:
Pacific: EWU, PSU, UCD, Sac, CP and NAU
Mountain: UM, MSU, UI, ISU, WSU and UNC
