If you watch a quarterback drop back, scan the field, and fire a laser downfield to a sprinting wide receiver, you are watching the most famous play in American football: the forward pass.
But if you’ve ever watched a game end with a desperate team tossing the ball backward five times in a row like a chaotic game of hot potato, you’ve witnessed the lateral.
To the untrained eye, throwing a football is just throwing a football. But in the rulebook, a ball thrown forward and a ball thrown backward might as well be from two completely different sports. Let’s break down the rules of the passing game so you can watch like a pro.
1. The Forward Pass: One Shot Only
The forward pass is the ultimate weapon in modern football, but the rules around it are incredibly strict.
- The Direction: The ball travels toward the opponent’s end zone.
- The Limit: A team can only throw ONE forward pass per play.
- The Boundary: The pass must be thrown from behind the line of scrimmage (the invisible line where the play started). If a quarterback crosses that line and throws the ball forward, it’s a major penalty.
- The Safety Net: If a forward pass hits the ground without being caught, it is ruled an incomplete pass. The play is immediately dead, the clock usually stops, and the offense gets to try again on the next “down.”
A quarterback has to keep his eyes downfield while avoiding defenders, searching for an open receiver to launch that single, crucial forward pass.
2. The Lateral (The Backward Pass): Unlimited Chaos
A lateral (technically called a backward pass in the rulebook) is when the ball is thrown sideways or toward the passer’s own end zone.
- The Direction: Parallel to the yard line or backward. Even an inch forward makes it an illegal forward pass.
- The Limit: There is no limit. A team can lateral the ball 100 times on a single play if they want to.
- The Boundary: A lateral can be thrown from anywhere on the field. A quarterback can do it behind the line of scrimmage, or a wide receiver can do it 50 yards downfield after making a catch.
- The Danger Zone: This is the most important difference! If a lateral hits the ground, the play is NOT dead. It is treated exactly like a fumble. The ball is live, and whoever dives on it first gets possession.
Why Don’t Teams Lateral More Often?
If you can lateral an infinite number of times anywhere on the field, why don’t teams do it on every play like they do in rugby?
The answer is risk. Because a dropped lateral is a live ball, it is incredibly easy for the defense to steal it and run it back for a touchdown. Football coaches are notoriously risk-averse; they would much rather take a safe, dead-ball incomplete forward pass than risk a catastrophic turnover on a messy lateral.
Summary Checklist for Beginners
| Rule Feature | Forward Pass | Lateral (Backward Pass) |
| Direction | Toward opponent’s end zone | Sideways or backward |
| How many per play? | Max of 1 | Infinite |
| Where can you throw it? | Only from behind the line of scrimmage | Anywhere on the field |
| What if it hits the ground? | Play is dead (Incomplete) | Live ball (Fumble!) |
The next time you see a frantic, last-second play with players tossing the ball wildly backward to keep the game alive, you’ll know exactly why they are doing it, and why the coach on the sideline is holding their breath!
