Has an AFL game ever ended 74-38?
Exactly once. On June 16, 1923, Fitzroy beat St Kilda 74-38, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 74-38 in league history.
That makes 74-38 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 75-38 has happened 1 times and 74-39 has happened 3 times.
