Has an AFL game ever ended 100-38?
Exactly once. On September 2, 1978, Geelong beat Fitzroy 100-38, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 100-38 in league history.
That makes 100-38 the 3884th most common final score out of 6,649 that have ever occurred in AFL. One point away, 101-38 has happened 1 times and 100-39 has happened 1 times.
