Has an AFL game ever ended 36-23?
Exactly once. On May 7, 1955, Footscray beat Essendon 36-23, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 36-23 in league history.
That makes 36-23 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 37-23 has happened 1 times and 36-24 has happened 1 times.
