After reviewing teams from the Sunbelt, AAC, CUSA, MWC, and MAC I came up with this list: ULM, Marshall, Tulsa, Cincinnati, Louisville, and Central Florida.
If I am not making the assumption that 2 losing seasons in a row also occurred during the three decades then you can add Air Force, Fresno St, and Toldeo to the list. This was based on results from 1982 to last years season. I do not currently have the time to review the rest of the conferences.
