do players get a cap for every game
The act of awarding a cap is now international and is applied to other sports. Although in some sports physical caps may not now always be given (whether at all or for each appearance) the term ``cap'' for an international or other appearance has been retained as an indicator of the number of occasions on which a sportsperson has represented a team in a particular sport. Thus, a ``cap'' is awarded for each game played and so a player who has played x games, for the team, is said to have been capped x times or have won x caps.
