# Interception

## Short Definition

A turnover where a defender catches a forward pass before it touches the ground—transferring possession and often reversing field position in a single play.

## Definition

An interception occurs when a defender catches a forward pass before it touches the ground—establishing possession mid-air and immediately converting the defense into the offense at the spot of the catch. The intercepting defender becomes the ball carrier and can attempt to advance the ball for additional yardage or a defensive touchdown. The possession change is immediate: the moment the defender secures the ball, the series ends for the offense and a new series begins for the defense.

The field position impact of an interception often exceeds the yardage numbers. An interception returned from the defending team's own 20-yard line to the 40 generates 20 yards of visible return yardage—but the full field position swing includes the 30 or 40 yards of drive the offense had accumulated before throwing the pass. An offense that drives from its own 20 to the opponent's 35 before throwing an interception at the 35 has effectively surrendered 55 yards of field position from where the drive started, though only 20 yards of that appears in the return stats. The real cost is the full drive's worth of accumulated field position given back in one play.

Interception probability is one of the most studied inputs in quarterback evaluation. A quarterback who converts a high percentage of throws into completions but concentrates his incompletions in interceptions—as opposed to incomplete passes that retain possession—costs his team significantly more than the raw completion percentage suggests. Expected points added on interceptions is among the most negative single-play values in football, reflecting both the lost possession and the likely field position swing.

The technical requirement for an interception differs from a reception by the offense in one critical way: the ground can cause an incomplete pass for an offensive receiver, but the ground cannot cause a dropped interception. A defender who catches the ball clearly, maintains possession through the fall, and has the ball come loose when hitting the ground has committed a fumble that may be recoverable—but the initial catch was an interception. A defender who never fully controls the ball before it hits the ground has not recorded an interception.

## Example

"Corner reads the release—the quarterback's shoulder turned to the out route before the ball left his hand. Corner breaks before the throw. Ball arrives, corner catches it in stride. Interception. The read started before the snap. The corner was never reacting to the ball; he was anticipating the throw."

## Common Confusion

A tipped pass that falls to the ground is an incomplete pass—not an interception. The defender must establish full possession for it to be ruled an interception. A ball that deflects off a defender's hands and is caught by another defender before hitting the ground is also an interception. The ground cannot make the catch.
