Has an AFL game ever ended 80-34?
Exactly once. On July 6, 1963, Hawthorn beat Richmond 80-34, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 80-34 in league history.
That makes 80-34 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 81-34 has happened 2 times and 80-35 has happened never.
