Has an AFL game ever ended 50-44?
Exactly once. On May 25, 1912, Melbourne beat Carlton 50-44, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 50-44 in league history.
That makes 50-44 the 3884th most common final score out of 6,649 that have ever occurred in AFL. One point away, 51-44 has happened 1 times and 50-45 has happened 3 times.
