LINEBACKER BOX DRILL TRAINING SUMMARY

This training focuses on developing linebacker footwork and block engagement techniques through progressive drill work. The box drill teaches linebackers to navigate different movement patterns including shuffles, crossovers, hip turns, and 45-degree drops while simulating coverage responsibilities. The drill also incorporates downhill pressing where players must plant, brake, and change direction effectively.

SHOCK LINES DRILL PROGRESSION

The core teaching method uses a three-phase approach starting from the collision point and working backward. Players are partnered up with one acting as a simulated blocker positioned on any yard line facing the end zone, while the linebacker shades behind them.

Phase 1 involves teaching proper foot placement with the near foot forward. On the first whistle, linebackers take a short step and load weight onto the near foot to engage hips and legs. On the second whistle, they explode through hips and hands with proper hand placement to make contact.

Phase 2 focuses on escape techniques to avoid wrestling matches at the collision point. After striking with the near hand on the sternum and far hand on the bicep, players create separation through explosion and lockout. They then throw the blocker through their near hip and step past with speed and control.

DEPTH DESTRUCTION TRAINING

The advanced phase moves linebackers back to five yards of depth, requiring them to master body control and proper foot placement while approaching the collision point. This teaches the critical skill of transitioning from depth to proper contact position on the fly. Improper foot alignment at contact gives offensive linemen significant leverage advantages regardless of the linebacker's physical superiority.

KEY COACHING POINTS

The training emphasizes that hand contact must be a collision rather than a press or grab motion. Hands should have velocity and create audible impact with the target, simulating the explosion needed to stop a blocker's feet and create escape opportunities. Various equipment can be used including medicine balls, shields, shot sleds, or even full-pad simulation without equipment for proper hand placement practice.

The drill system allows for easy setup and high repetition training, making it valuable for programs needing to develop multiple players efficiently throughout the season.
