Possession (sports) determined by several methods, including a coin flip (American football and cricket), home team status (baseball), or by giving the teams an equal opportunity to physically take possession; this may be called a dropped-ball (association football), a ball-up (Australian rules football), a jump ball (basketball), or a face-off (hockey). In some timed sports, the team with possession may try to "run time off the clock" by keeping the ball and not attempting to score, in order to deny the opposing team possession. A shot clock speeds gameplay by requiring teams to attempt to score within a certain period of time
