Has an AFL game ever ended 85-46?
Exactly once. On June 25, 1921, Fitzroy beat Essendon 85-46, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 85-46 in league history.
That makes 85-46 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 86-46 has happened 2 times and 85-47 has happened 3 times.
