Has an AFL game ever ended 75-37?
Exactly once. On June 1, 1918, Carlton beat Essendon 75-37, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 75-37 in league history.
That makes 75-37 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 76-37 has happened 1 times and 75-38 has happened 1 times.
