Has an AFL game ever ended 90-44?
Exactly once. On April 19, 2003, Geelong beat Melbourne 90-44, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 90-44 in league history.
That makes 90-44 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 91-44 has happened 1 times and 90-45 has happened 1 times.
