BLOCK DESTRUCTION AND EDGE SETTING TECHNIQUES FOR DEFENSIVE BACKS

This coaching video focuses on teaching defensive backs how to properly set the edge and destroy blocks on perimeter plays, particularly bubble screens.

HARD JOINT TECHNIQUE FUNDAMENTALS

The core technique for attacking kickout blocks involves attacking the blocker with the near foot and near shoulder while keeping cleats in the grass. The key is to hold your ground and not get washed down the line, setting a solid edge for the defense. Players must maintain their outside arm free to make tackles if the ball bounces outside.

BUBBLE DRILL PRACTICE

The team runs bubble drills against their offense multiple times per week to replicate game situations. Proper execution includes:

• Recognizing the bubble screen quickly
• Attacking the blocker and creating knockback
• Setting a wall on the outside perimeter
• Shedding the block to get involved in the tackle

COMMON MISTAKES TO AVOID

The video includes examples of poor technique, specifically when defenders try to sling blockers and turn their body, exposing their back to the sideline. Players must stay square to the line of scrimmage and keep their feet planted while using the hard joint technique.

FORMATION RECOGNITION AND ANTICIPATION

Defensive backs should anticipate plays based on formation tendencies, receiver splits, and alignments. Examples shown include recognizing when receivers are deeper than normal or when tight ends are positioned as bigger blockers, indicating potential bubble screens or RPOs.

FINISH THE PLAY

The emphasis is on going beyond just forcing the ball inside—players must beat the block and make the tackle themselves. Setting the edge isn't enough; defensive backs need to show fanatical effort, strain to the ball, and finish plays rather than simply doing the minimum.

USE THE SIDELINE

Proper leverage includes using the sideline as an extra defender, positioning yourself as wide as possible without going out of bounds to eliminate outside running lanes.
