what determines which state of origin team you play for
State of Origin series Players are selected to represent the Australian state in which they played their first senior rugby league game, hence the name 'state of origin'. Prior to 1980 players were only selected for interstate matches on the basis of where they were playing their club football at the time. In both 1980 and 1981 there were two interstate matches under the old selection rules and one experimental "State of Origin" match. From 1982 onwards a best-of-three match series has been played around the middle of the rugby league season for the State of Origin shield. During the early years, the results were extraordinarily even. However, since 2006, Queensland has won every series except in 2014.
England national under-21 football team This team is for English players aged under 21 at the start of the calendar year in which a two-year European Under-21 Football Championship campaign begins, so some players can remain with the squad until the age of 23. As long as they are eligible, players can play for England at any level, making it possible to play for the U21s, senior side, and again for the U21s, as Jack Butland, Harry Kane, Calum Chambers and John Stones have done recently. It is also possible to play for one country at youth level and another at senior level (providing the player is eligible).
