Has an AFL game ever ended 69-40?
Exactly once. On June 12, 1909, Carlton beat St Kilda 69-40, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 69-40 in league history.
That makes 69-40 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 70-40 has happened never and 69-41 has happened 2 times.
