Greenbrier High moved to Cunniff Drive
The Village Green records the high school’s move into the new Cunniff Drive facility in fall 1980. The football season therefore sits inside a larger campus transition, not just a change on the schedule.

5–5, four shutouts and a plus-17 point margin
Greenbrier blanked Cheatham, Macon, DeKalb and Jo Byrns. Mike Clark’s three touchdowns beat White House, while Portland’s 8–7 comeback decided the district race.
The complete schedules hold at 31–0 and 34–0
The DeKalb headline prints 35–0, but the page’s scoring lines total 31. The Trousdale headline prints 32–0. In both cases, the school list and independent season schedule agree with the retained 31–0 and 34–0 finals.
