Running out the clock
In American football, each quarter of a game is measured with a 15-minute game clock, or 12-minute clock in many high school football codes and the German Football League. A team in possession of the lead and the ball will attempt to use up as much of the game clock as possible in order to bring the game to an end more quickly, thus denying the opposition another chance on offense.
Indiana High School Rugby
Unlike senior level clubs, which play two forty-minute halves, youth rugby in the United States is capped below the traditional eighty-minute match. In Indiana, matches are scheduled for two thirty-minute halves, with players not allowed to participate in more than ninety minutes of scheduled match time in a single day. In competitions in which teams compete in multiple matches, the total length of the match is truncated to comport with the ninety-minute daily cap, thus, the matches are contested at two halves each of 22.5 minutes in duration. Matches consist of fifteen players on the field for each team along with eight reserves on the bench (23 total). Matches will end in a draw if level at the end of full-time unless in a championship competition. In a championship competition, if the match is level at full-time, an additional ten-minute sudden death period is played. If the match remains level after sudden death, then the outcome is decided on drop kicks. If multiple matches are to be contested in a single day, the sudden death period is foregone. Coed play at the high school level is not permitted. The coed prohibition was tested in May 2001 by the Mishawaka High School boys squads' attempt to include Nicole Kodba in its playoff lineup. Despite arguments from her coach and a community petition, Kodba was not allowed to compete for the boys team.
