# Stalk Block

## Short Definition

A wide receiver's technique for blocking a defensive back in open field on run plays—approaching under control, mirroring the defender, and sustaining contact.

## Definition

A stalk block is the technique a wide receiver uses to block a defensive back in the open field on run plays—particularly outside runs, jet sweeps, and perimeter runs where the receiver's alignment puts him in position to engage the cornerback or safety responsible for the edge. The block is essential to perimeter run success: without it, the defensive back is free to flow to the ball and make an unobstructed tackle, limiting the run to whatever yardage the initial cut provided.

The stalk block requires the receiver to approach the defender under control—at full speed initially, then decelerating into a body-control position approximately two yards from the defender. The receiver cannot approach at a dead sprint because the defender will simply sidestep him; the approach must be controlled enough to mirror the defender's lateral movement and maintain an engaged blocking position. Once the receiver closes to contact distance, he drives through the defender's inside number, sustaining contact and preventing the defender from reaching the ball carrier.

Footwork is the technical foundation of the stalk block. The receiver must short-step to stay balanced as he closes, keep his pad level low to prevent the defender from shedding him with a push, and work his feet through contact rather than lunging with his upper body—a receiver who lunges falls off the block instantly. The sustained position—pads low, feet churning, hands inside—is what gives the running back an additional cut lane after the initial contact.

Great stalk blocking receivers are specifically valued in outside zone and sweep offenses because perimeter runs require the corner to be accounted for. A receiver who can consistently seal a cornerback for even two seconds after the handoff converts a four-yard run into a ten-yard run. The block's value is multiplication: it converts good runs into explosive runs by eliminating the nearest outside threat.

## Example

"Outside zone to the left. X receiver runs a stalk block on the corner—approaches under control, gets position, drives him outside. The running back cuts behind the block and has open field. Without that stalk block the corner makes the tackle at three yards. With it, it's twelve."

## Common Confusion

A stalk block is not a crack block. A crack block has the receiver coming inside to block a linebacker or safety aligned outside—a block toward the interior from a wide receiver's alignment. A stalk block has the receiver going directly at a defensive back in the open field and engaging him at the point of contact. They involve different approach angles, different defender targets, and different techniques.
