Has an AFL game ever ended 84-28?
Exactly once. On August 31, 1963, Essendon beat Footscray 84-28, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 84-28 in league history.
That makes 84-28 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 85-28 has happened 1 times and 84-29 has happened 1 times.
