Has an AFL game ever ended 91-44?
Exactly once. On June 23, 1934, Melbourne beat Footscray 91-44, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 91-44 in league history.
That makes 91-44 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 92-44 has happened 4 times and 91-45 has happened never.
