Motion is one of the many ways an offense can attempt to deceive the defense by moving players around the formation before the ball is snapped. The different motions used in football and how they are performed legally can be confusing to those not familiar with the idea.
Motion in football is identified as the pre-snap movement by a player aligned off the ball in the backfield while the ball is snapped. Only one player is allowed to be moving at the snap of the ball, and they can only move laterally, not toward the line of scrimmage.

Legal Motion
Performing a motion legally is something that coaches and players even have trouble perfecting on Sundays. It is important to understand the difference between a motion and a shift when examining legal motions.
The offense is free to shift and move as many players as they want as long as they are all set for a full second before the ball is snapped.
This is different from motion because the player is allowed to be moving while the ball is snapped. Only one player is allowed to be moving in motion, and that movement must be lateral to the line of scrimmage.
No forward movement at the time of the snap is permitted
Types of Motion
Every weekend during football season, it seems that a team will find a new way to move a skilled player before the snap. While there are countless forms of motion, the ones displayed below are ones found in most playbooks.
Jet
Jet is a motion across the formation with the ball being snapped just before the player reaches the quarterback. This allows for players to perform outside run plays while already at full speed at the snap of the ball. This is also known as “Fly” motion in some terminology, especially out of the Wing-T.
Fly
Across motion is very similar to “Jet.” The main difference is that the ball is snapped after the player crosses to the other side of the formation.
Glide
Glide is a motion by a player in an original outside alignment towards the ball. The ball is snapped once the player is in the area of about halfway to the last attached player (or the end man on the line). This allows for momentum and speed into a crossing route, quick change of direction into an out-breaking route, or the ability to seal the outside on a run block.
In
This is a move into the backfield by a player from an outside alignment. There is usually a destination tag or word associated with this motion to tell the player where they are supposed to end up at the snap of the ball. For example, a gun, wing, or pistol could all be destinations for players using “In” motion.

Over
Over is usually performed by a tight end from one side of the backfield to the other. In general, it is a motion by a player in the backfield from one side of the formation to the corresponding spot on the opposite side.
Return
Return is built off of “Over” and “Across” motion. In Return, the player will cross over to the other side of the formation and then return to their original alignment at the snap of the ball.
Exit
This is a motion used by a running back as he leaves the backfield to a wide alignment. Exit is usually paired with a destination, for example, “Exit to Wide,” telling the back where they need to be in the formation.
Orbit
Orbit is another motion for the running back. This time the back will be in the shotgun, motion behind the quarterback, and move laterally down the line of scrimmage until the ball is snapped.
Rocket and Laser
Rocket and Laser are the same as “Orbit” minus passing behind the quarterback. The R and L in Rocket and Laser identify the right and left directional movement for the back. They start in the shotgun and move laterally down the line of scrimmage in the designated direction until the ball is snapped.

Slide
The slide is similar to the previous two motions but adds a forward movement before the lateral movement. The back will start in the shotgun at the hip of the quarterback, move up to the backside of the offensive line, and then laterally down the line to the side of the formation they are aligned. This does not violate motion rules as they are not moving towards the line at the snap of the ball.
Benefits of Motion
The reasons a team uses motion can fall under three different categories: momentum, deception, and leverage.
Momentum, or speed when the ball is snapped, allows for the player to already build up to full speed at the snap rather than starting from a set stance from a standstill.
This allows for sweep plays to hit faster off of jet motion, wheel routes to take off quicker off of orbit motion, and crack blocks to gain more force off of glide motion.
Deception is another advantage gained from motion. Flashing players across the formation can take the linebacker’s eyes off the ball and their read keys and away from the play.
Running a play that utilizes a certain motion can have the defense anticipating that play until you run a different concept off of that same motion leaving the defense confused and opened up for a big gain.
Finally, leverage gained with motion creates an edge for the offense. Motioning to a wider alignment for an easier outside release and moving into the backfield to better secure a block are advantages that motion brings to the table.
Other Notes on Motion
- There are endless ways to run different variations of motions, the number one thing to consider is the legality of the motion when incorporating it into the offense.
- Shifts are a great way to utilize multiple player movement pre-snap, just remember to be set for one full second before the ball is snapped.
- Many teams will pair the position with a shortened form of the motion for communication purposes. For example, teams that label the tight end as “Y” can use “YAC” for Y-Across motion and “YIN” for Y-In motion. If a team labels the running back as “T” those same principles can be applied to “TAC” (T-Across) and “TIN” (T-In) motion.
- Different teams will use different terminology for the same motions. That means you could see these same motions called different names depending on the system.

Who Created The Jet Sweep?
Motion has been around forever, but the modern jet sweep play is credited to being invented by Bob Stitts from the Colorado School of Mines in 2003. He incorporated the idea out of a shotgun formation, and it spread throughout the college ranks immediately after.
