Has an AFL game ever ended 43-32?
Exactly once. On May 16, 1908, Carlton beat Essendon 43-32, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 43-32 in league history.
That makes 43-32 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 44-32 has happened 3 times and 43-33 has happened 1 times.
