Has an AFL game ever ended 14-8?
Exactly once. On September 4, 1897, Essendon beat Melbourne 14-8, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 14-8 in league history.
That makes 14-8 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 15-8 has happened never and 14-9 has happened never.
