Has an AFL game ever ended 180-70?
Exactly once. On May 10, 1980, Richmond beat Footscray 180-70, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 180-70 in league history.
That makes 180-70 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 181-70 has happened never and 180-71 has happened never.
