American football plays
In American football, a play is a close-to-the-ground plan of action or strategy used to move the ball down the field. A play begins at either the snap from the center or at kickoff. Most commonly, plays occur at the snap during a down. These plays range from basic to very intricate. Football players keep a record of these plays in a playbook.[1]
A play begins in one of two ways:
Once the play begins, it will continue until one of the following events happens:
When the play ends, the ball is set for the next play. For the first three instances above, the ball is set at the point of its maximum forward progress. That means that if a runner is driven back in the process of a tackle OR is ruled down by lack of forward progress, the ball is placed as close to his opponent's goal line as he had gotten before being driven back. If he runs backwards of his own volition, the ball is marked where he goes down. In the case of an incomplete pass, the ball is placed at the previous line of scrimmage.
Play then resumes as described above.
