Has an AFL game ever ended 44-17?
Exactly once. On July 13, 1918, St Kilda beat Carlton 44-17, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 44-17 in league history.
That makes 44-17 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 45-17 has happened never and 44-18 has happened 2 times.
