Has an AFL game ever ended 57-16?
Exactly once. On June 2, 1991, Footscray beat Carlton 57-16, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 57-16 in league history.
That makes 57-16 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 58-16 has happened never and 57-17 has happened never.
