I've been going through the NAFC player/game database and stumbled upon something I knew nothing about (that's not that unusual)
In 1919 North not only drew the Grand Final with West Torrens and had to replay it the following week, a week after the replay they also drew the Challenge Final against Sturt (who'd finished top in the minor round and challenged North for the title after they won the GF replay) and had to replay it again a week later
Another interesting statistic from the 4 matches, all 4 games had equal scoring shots, the straighter kicking side won each challenge final
