Has an AFL game ever ended 149-63?
Exactly once. On April 8, 1972, Richmond beat Geelong 149-63, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 149-63 in league history.
That makes 149-63 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 150-63 has happened never and 149-64 has happened never.
