Has an AFL game ever ended 67-19?
Exactly once. On July 16, 1898, Fitzroy beat St Kilda 67-19, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 67-19 in league history.
That makes 67-19 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 68-19 has happened 1 times and 67-20 has happened never.
