Has an AFL game ever ended 187-79?
Exactly once. On April 5, 1987, Sydney beat Footscray 187-79, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 187-79 in league history.
That makes 187-79 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 188-79 has happened never and 187-80 has happened never.
