Quarterback

The usual position of the quarterback is in blue

A quarterback (QB) is a position in American and Canadian football. Quarterbacks are members of the offense, or attacking team. They line up directly behind the center, in the middle of the offensive team's line. A quarterback is usually the leader, and starts most plays. In addition, the quarterback gives commands to the other players before the start of a play. A quarterback will in most attacking plays throw the ball to a member of their team, ready to run to the end of the pitch. Quarterbacks may also run the ball themselves, as well as hand the ball to a runningback. These players are usually the faces of their respective teams. Some very notable players at this position in history are Tom Brady, Jim Kelly, and Peyton Manning.

Special tactics

If quarterbacks don't like the formation the defense is using, they may use an audible. An audible is a way for the quarterback to change the play at the line of scrimmage (where players line up to start a play). He changes what the play will be by shouting out things that his teammates will understand. An audible may be called if the quarterback sees how the defensive players are lined up and does not think that the play that has been called would be good against how the defense is lined up.

Like many early formations, the quarterback did not receive the ball from center, and instead served as a blocking back. In modern football, the single-wing is only used as a primary offense by a small number of high school teams.
