Wide Receivers

A wide receiver (also referred to as wideouts or simply receivers) is an offensive position in American and Canadian football, and is the key player in most of the passing plays. They get their name because they are split out "wide" (near the sidelines), furthest away from the rest of the team. Wide receivers are among the fastest players on the field. The wide receiver functions as the pass-catching specialist.

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 (typically cornerbacks and/or safeties) in the area of his pass route. If the receiver becomes open, or has an unobstructed path to the destination of a catch, he may then become the quarterback's target. Once a pass is thrown in his direction, the receiver's goal is to first catch the ball and then attempt to run downfield. Some receivers are perceived as a deep threat because of their flat-out speed, while others may be possession receivers known for not dropping passes, running crossing routes across the middle of the field, and generally, converting third down situations. A receiver's height and weight also contribute to his expected role; tall height and light weight are advantages at the receiver position.

A wide receiver has two potential roles during running plays. Particularly in the case of draw plays and other trick plays, he may run a pass route with the intent of drawing off defenders. Alternatively, he may block normally for the running back. Well-rounded receivers are noted for blocking defensive backs in support of teammates in addition to their pass-catching abilities.

Sometimes wide receivers are used to run the ball, usually in some form of end-around or reverse. This can be effective because the defense usually does not expect them to be the ball carrier on running plays. For example, wide receiver Jerry Rice rushed the ball 87 times for 645 yards and 10 touchdowns in his 20 NFL seasons.
