Has an AFL game ever ended 231-74?
Exactly once. On April 28, 1991, Hawthorn beat Fitzroy 231-74, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 231-74 in league history.
That makes 231-74 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 232-74 has happened never and 231-75 has happened never.
