Has an AFL game ever ended 101-71?
Exactly once. On May 24, 2003, Fremantle beat Melbourne 101-71, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 101-71 in league history.
That makes 101-71 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 102-71 has happened 6 times and 101-72 has happened 6 times.
