Midland Junction — were "casualties" of the war, competing for the last time in 1915 and 1917 respectively. Between the Wars In 1921, the WAFL introduced the Sandover Medal, for the fairest and best player over a season, as voted by the field umpires. The medal has been awarded annually ever since. Claremont entered the league in 1926, bringing the number of teams back to seven. In 1932, the WAFL was renamed the Western Australian National Football League (WANFL) - the "national" concept in the name being adopted by the SANFL and a couple of other leagues a few years earlier. Swan Districts entered the league in 1934. The eight competing sides still remain today and are generally referred to as the "traditional eight clubs". Because of World War Two, the league only ran an "under age" competition between 1942–44. However, the three premierships won during this time are given equal status to any other, in official records. All clubs competed, with the exception of Swan Districts who could not form a team in 1942, although they were back in 1943. Post-war period The 1960s saw crowds get bigger and bigger, as WAFL football captured the hearts and minds of the WA public like never before, and in the 1970s and early 80s it was easily the biggest show in town. However, during this period more and more star WAFL players were looking to head to the Victorian Football League (VFL), enticed by the bigger money and the fact that it was more and more gaining a reputation as the "big" league. This is perhaps best evidenced in that Victoria (i.e. the VFL representative team) had by far the best record in interstate games for a long time. But in 1977, when the first proper State of Origin match was played, it saw Western Australia inflict its biggest defeat on a Victorian team. In 1980, the WANFL dropped the "N" and the "ern" and reverted to being called the WAFL. At this time crowds were as big as they ever were. Soon afterwards, however, interest in the WAFL began a slow decline, as it became increasingly obvious that even larger numbers of the WAFL's best players were going to head east. Entering the National Competition By 1987, the WAFL had decided that the future of the game in WA depended on it entering a team in the VFL. The West
