Has an AFL game ever ended 79-36?
Exactly once. On September 16, 1905, Fitzroy beat Essendon 79-36, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 79-36 in league history.
That makes 79-36 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 80-36 has happened never and 79-37 has happened 1 times.
