Has an AFL game ever ended 75-64?
Exactly once. On May 1, 1954, Hawthorn beat Melbourne 75-64, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 75-64 in league history.
That makes 75-64 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 76-64 has happened 2 times and 75-65 has happened 6 times.
