Has an AFL game ever ended 72-24?
Exactly once. On June 5, 1897, Geelong beat Sydney 72-24, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 72-24 in league history.
That makes 72-24 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 73-24 has happened never and 72-25 has happened never.
