The quarterback is usually considered the leader of the offensive team, and is often responsible for calling the play in the huddle.
The wide receiver's principal role is to catch passes from the quarterback. On passing plays, the receiver attempts to avoid, outmaneuver, or simply outrun defenders in the area of his pass route.
Linebackers are members of the defensive team, and line up approximately three to five yards (4 m) behind the line of scrimmage, behind the defensive linemen, and therefore "back up the line."
