It should have been a school decision not a conference decision. If the entire conference votes yes, then the conference season can proceed. If a conference is split, all teams voting yes play a fall season against in conference and OOC teams that voted yes. Teams that vote no, can play in the spring against other in conference and OOC teams that voted no.
Split conferences simply cancel their season in response to COVID which is an act of god (gets out of contracts); don't prohibit other schools from acting independently after the season is cancelled.
I'd rather be playing this fall for a bowl game or just because more than I would the spring for MWC championship.
