a rush play. The player then passes the ball back to the quarterback, who throws it to the receivers. Properly timed, the defensive team will have started responding to the rush by moving forward, leaving the receivers wide open. However, timing the play is difficult, and with two lateral passes and a forward throw, the chances for error are great. A failure leaves the ball behind the line of scrimmage in what will almost certainly be a loss of yards. The play also requires all passes prior to the final one thrown by the quarterback to be either parallel to the line of scrimmage or backwards, since only one forward pass is allowed per play. Multiple forward passes will result in a penalty. Common trick plays Common trick plays attempt to place the defense out of position by starting action in one direction, then completing it in another. They often appear to be a conventional play at first. There is no real "trick" being played in terms of deception, the defense simply reacts without considering the possibility of the ball carrier changing mid-play. Some of these plays are so common as to not be recognized as trick plays, instead being a regular part of the American football playbook. Play Action Pass One of the most common forms of deception is the use of a play action pass, commonly referred to as a "play fake". In this type of play, after the snap the quarterback appears to hand the ball to the halfback, who will then simulate running with the ball. Still in possession of the ball, the quarterback will then attempt to complete a pass play. A play action pass can be effective in bringing linebackers and even defensive backs up close to the line of scrimmage in hopes of stopping a run, leaving receivers with more room to run routes and catch the ensuing pass. Draws A draw is, in essence, the opposite of a play action pass and can be as common. After the snap, the quarterback simulates the action of a pass, including dropping back and looking down field for the receivers. The quarterback will then hand the ball off to a running back or keep the ball himself and rush forward. A draw play attempts to fool the defense into dropping back into pass coverage, putting them out of position to cover the eventual rushing play.
