Has an AFL game ever ended 135-80?
Exactly once. On June 4, 1994, Carlton beat Fitzroy 135-80, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 135-80 in league history.
That makes 135-80 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 136-80 has happened never and 135-81 has happened 4 times.
