Slot is a term used to describe the space on the football field between the tight end or offensive lineman and the wide receiver. It is a critical part of the running game and is essential for passing plays that involve sweeps or slants.

A slot receiver has to be able to run precise routes, and their positioning on the field is crucial for this. Because they have to line up a few yards behind the line of scrimmage, they have to be really fast and possess great route-running skills. They also have to be able to seal off the outside part of the field so that their blocking can be effective.

The slot receiver usually lines up behind the middle of the offensive line, a few yards from the center of the field and opposite the boundary. He is a threat to do virtually anything when on the field and can stretch the defense vertically by getting past the defensive backs.

He is often called into pre-snap motion by the quarterback, which gives him a full head of steam before the ball is handed off or the snap is executed. This allows him to get out of the way of the defense’s best tacklers and open up the rest of the field for the offense.

On running plays, a slot receiver will often block on his own (or with a chip block) to protect the quarterback and ensure that he gets the football out of the backfield quickly and easily. They will typically block nickelbacks, outside linebackers, and safeties, depending on the specific running play. They may even perform a crack back block on defensive ends to help prevent a running play from going to the ground.

They are also important on passes because they can confuse the defense by running routes that match up with the receivers in front of them. They can also be called into pre-snap motion to help the quarterback get the ball out of the backfield.

These players are called into pre-snap motion for certain running plays, such as pitch plays, reverses, and end-arounds. This allows the quarterback to get the ball out of the backfield quickly and easily, while allowing the Slot receiver to be a huge decoy for future runs.

Some slot receivers will also carry the ball from time to time. This is especially useful when the quarterback is using a deep passing game to open up the defense, since they can act as a target for the receivers in front of them.

A slot receiver can also be used as a decoy for other players on the field, such as a kicker or running back. On kickoffs, a slot receiver is often called into pre-snap for a return. This allows the team to use a decoy to take advantage of the other team’s blitzing linebackers or tight ends, or for the quarterback to throw the ball over the top of the receivers.
