Has an AFL game ever ended 145-84?
Exactly once. On August 3, 1996, Carlton beat Fremantle 145-84, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 145-84 in league history.
That makes 145-84 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 146-84 has happened 6 times and 145-85 has happened never.
