Has an AFL game ever ended 140-50?
Exactly once. On August 6, 1927, Melbourne beat Essendon 140-50, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 140-50 in league history.
That makes 140-50 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 141-50 has happened 1 times and 140-51 has happened never.
