Has an AFL game ever ended 108-14?
Exactly once. On May 7, 1904, Fitzroy beat Carlton 108-14, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 108-14 in league history.
That makes 108-14 the 3884th most common final score out of 6,649 that have ever occurred in AFL. One point away, 109-14 has happened never and 108-15 has happened never.
