Has an AFL game ever ended 80-47?
Exactly once. On April 21, 1962, Footscray beat Hawthorn 80-47, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 80-47 in league history.
That makes 80-47 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 81-47 has happened 3 times and 80-48 has happened 1 times.
