Has an AFL game ever ended 102-41?
Exactly once. On May 14, 1966, Carlton beat Essendon 102-41, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 102-41 in league history.
That makes 102-41 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 103-41 has happened never and 102-42 has happened never.
