The rivalry with Victoria stems from before State of Origin started, when the standard rules prior to 1977 was that all VFL players played interstate football for Victoria. As most of the country's best players played in the VFL, Victoria dominated the pre-State of Origin era, it created a culture of disdain towards Victoria. Another component of the rivalry is a historical feeling in South Australia that Victoria doesn't rate any player or league outside Victoria. Another contributing factor is a feeling in South Australia that Victorians think they own the game.
