Didn't say in the article, but Football would have:
Rock Port
East Atchison (Tarkio/Fairfax)
Northwest Nodaway (North Nodawy/West Nodaway)
Mound City (co-op with Craig)
Nodaway-Holt (co-op with South Holt)
DeKalb
Stewartsville (co-op with Osborn)
Southwest Livingston (co-op with Breckenridge and Hale)
South Nodaway (co-op with Jefferson)
Basketball would have:
Rock Port
Tarkio
Fairfax
North Nodaway
West Nodaway
Mound City (co-op with Craig)
Nodaway Holt
South Holt
DeKalb
Stewartsville
Osborn
South Nodaway
Jefferson
Northeast Nodaway
Union Star
Of course, there could be changes in co-ops that could change things. Northeast Nodaway currently co-ops with Worth County and Union Star currently co-ops with King City who are both GRC members. They may op to join with 275/PVC members in the future. The other wildcard is possible future school consolidations.
