Has an AFL game ever ended 67-50?
Exactly once. On September 18, 1954, Melbourne beat Geelong 67-50, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 67-50 in league history.
That makes 67-50 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 68-50 has happened 7 times and 67-51 has happened 2 times.
