As the game of American football continues to capture a growing global audience—especially with passionate fans tuning in from the UK and beyond—getting to grips with the official rulebook is part of the journey.
If you have ever watched a chaotic final-play sequence where the ball is flung frantically backward from player to player, you might find yourself asking a fundamental question: If teams can move the ball backward as many times as they want, why don’t they just keep passing it around on every single play?
Understanding the difference between a forward pass and a backward pass unlocks one of the most thrilling strategies in professional football.
Let us break down the absolute limits of throwing and tossing the ball in the National Football League, examine why teams do not constantly lateral the ball, and analyze those rare, unforgettable moments when multiple passes completely change the outcome of a game.
The Core Rule: One Forward Pass Per Down
To understand why offenses cannot simply throw the ball all over the field at random, we have to start with the single most important restriction in the passing game: the one-forward-pass limit.
According to official league regulations, an offensive team is strictly permitted to complete only one forward pass during a single play from scrimmage.
The Origin: The pass must be thrown from behind the line of scrimmage. Once any part of the passer’s body or the ball crosses the imaginary line marking the line of scrimmage, throwing the ball forward becomes illegal.
The Penalty: If a quarterback or any other player throws a second forward pass on the same down, it results in an illegal forward pass penalty. This typically costs the offense 5 yards and results in a loss of down.
Incomplete Passes: If that single allowed forward pass touches the ground without being caught, the play is immediately dead, and it is ruled an incomplete pass, stopping the game clock.
Because of this strict limitation, offenses cannot treat every play like a backyard game of catch. Once the quarterback launches that one forward pass, the aerial element of the play is effectively locked in.
The Loophole: Uncapped Backward and Lateral Passes
While the forward pass is heavily restricted, the rulebook takes a completely different approach to backward passes and lateral passes.
If a player decides to throw, toss, or hand the ball parallel to the line of scrimmage or directly backward toward their own end zone, the rules change entirely:
Unlimited Attempts: There is no limit to how many backward or lateral passes a team can execute during a single play. An offense could theoretically throw ten backward passes in a row if they had the coordination and time to do so.
Anywhere on the Field: These passes can occur anywhere on the playing surface, whether behind the line of scrimmage or fifty yards downfield.
The Massive Risk (The Live Fumble): This is the ultimate catch—and the primary reason teams rarely use backward passes on standard plays. Unlike an incomplete forward pass, which safely stops the clock and returns the ball to the line of scrimmage, if a backward pass hits the ground, it is treated as a live fumble. Any member of either team can recover it, meaning a botched lateral can instantly turn into a disastrous turnover or a defensive touchdown.
Why Don’t Teams Pass the Ball Around on Every Play?
Given that backward passes are completely legal and unlimited, casual fans often wonder why offenses do not incorporate constant laterals into their regular playbooks to confuse defenses.
The reality comes down to risk, physics, and the sheer speed of professional athletes. Here is why the multi-lateral play is a massive gamble:
1. The High Probability of Turnovers
In the NFL, defenders are among the fastest and hardest-hitting humans on the planet. When an offensive player catches a pass, their primary focus is securing the ball and bracing for contact.
Asking players to immediately pitch or toss the ball backward while moving at full speed dramatically increases the odds of a dropped ball, a misdirected toss, or a direct fumble to the opposing team.
2. Loss of Yardage
Unlike a forward pass—which usually gains ground or travels through the air toward the opponent’s goal line—a backward pass inherently moves sideways or backward.
Every lateral risks pushing the offense further away from the first-down marker. If a team tries three or four backward passes and gets tackled, they often end up losing significant yardage.
3. Defensive Containment
NFL defenses are meticulously coached to read plays and pursue the ball carrier. If an offense starts lateral-hunting in open space, defenders converge rapidly from all angles.
Without the protection of standard blocking schemes designed for a traditional running or passing play, lateral chains usually get trapped near the sideline.
The Exception to the Rule: The Miracle Lateral Plays
Because backward passes carry such high risk, teams rarely use them during normal game flow. However, there is one specific scenario where teams throw caution to the wind: desperation plays at the end of a half or the end of a game.
When a team is trailing as the game clock expires, they have nothing left to lose. They will execute a standard forward pass or a short completion, and immediately begin pitching the ball backward to teammates to keep the play alive.
The Classic Example: The 2018 Miami Miracle
Fans who have followed the sport for years often point to legendary moments like the 2018 game between the Miami Dolphins and the New England Patriots.
- With the game on the line and only seconds remaining on the clock, Miami executed a desperate multi-lateral play.
- The quarterback completed a short pass over the middle, and the receiver immediately lateraled the ball to a teammate.
- That second player ran toward the sideline, drew defenders, and pitched the ball a second time backward to running back Kenyan Drake, who sprinted past the remaining angles of the defense down the sideline to score a dramatic, game-winning touchdown as time expired.
This famous sequence proves that while passing the ball around multiple times is legal, it requires absolute precision, flawless timing, and an incredible amount of luck to pull off successfully.
Frequently Asked Questions
Can you throw a forward pass after catching a backward pass?
Yes. As long as the team has not yet thrown a forward pass on that specific down, any player who receives a backward pass behind the line of scrimmage can still choose to throw a forward pass.
This is a common mechanism used in trick plays, such as a wide receiver pass or a halfback option play.
What happens if a lateral goes forward by mistake?
If a player attempts a lateral or backward pass, but the ball actually travels forward through the air, it is officially ruled an illegal forward pass (assuming the team has already thrown one, or if the pass was thrown from beyond the line of scrimmage). This draws a penalty and stops the play.
Can a quarterback spike the ball to stop the clock more than once?
No. Spiking the ball to stop the clock counts as a forward pass. Because an offense is limited to one forward pass per down, spiking it a second time would result in an intentional grounding or illegal forward pass penalty.
Conclusion
The rules governing passes in professional football create a brilliant balance between strategy and safety.
By restricting teams to one forward pass per down, the league keeps the game structured and manageable for officials and players alike.
At the same time, allowing unlimited backward passes opens the door for breathtaking, chaotic, last-second heroics that keep fans on the edge of their seats.
So, while you won’t see teams passing the ball around like a basketball team during a standard drive, knowing the lateral rules helps you appreciate just how remarkable those rare, miraculous plays truly are when they succeed.
