Has an AFL game ever ended 117-15?
Exactly once. On August 10, 1963, St Kilda beat Fitzroy 117-15, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 117-15 in league history.
That makes 117-15 the 3884th most common final score out of 6,649 that have ever occurred in AFL. One point away, 118-15 has happened never and 117-16 has happened never.
