Has an AFL game ever ended 35-30?
Exactly once. On July 16, 1904, Essendon beat Melbourne 35-30, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 35-30 in league history.
That makes 35-30 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 36-30 has happened never and 35-31 has happened never.
