Has an AFL game ever ended 44-13?
Exactly once. On May 26, 1906, St Kilda beat Essendon 44-13, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 44-13 in league history.
That makes 44-13 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 45-13 has happened 1 times and 44-14 has happened never.
