Has an AFL game ever ended 36-11?
Exactly once. On May 20, 1899, Geelong beat Carlton 36-11, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 36-11 in league history.
That makes 36-11 the 3884th most common final score out of 6,649 that have ever occurred in AFL. One point away, 37-11 has happened never and 36-12 has happened never.
