No team can call two timeouts in a row on the same scrimmage down.
Football Timeout Strategy
A team will use a timeout:
Teams call timeouts to stop the game clock from ticking. This is done to save time for a chance to score.
Time is important in football. More time on the clock means more chances to score. Teams will save time, especially when the score is close.
Football Delay Of Game
Teams will call a timeout to prevent a Delay of Game penalty. A team will call a timeout if they are not on the field when the play clock nearing 0:00.
Teams will call a timeout to ice a player in hopes of them making a mistake.
The best example of this is when a team ices the opposing team's kicker. Just before a kick is made, a player or coach on a football team will call a timeout. There is a possibility that the kicker will make a mistake on the next play.
