Adaptability is one key to shutting down complex offensive schemes. The FAST system—Force, Attack, Slam, Track—provides coaches with an easy to teach approach to run fits that can neutralize even the most dynamic multi-formation offenses

Donald Davis, Head Coach, Mount Saint Joseph HS (MD), presents his system on Glazier Drive: 4-2-5 Run Fits to Defend vs. Multiple Formations/Personnel Sets & Using the Force Defender to Add to Basic Blitz Package.

The video below is a segment of that complete video.

The video discusses the FAST (Force, Attack, Slam, Track) defensive strategy for handling run plays and RPOs across different defensive formations. Key points include:

Defensive Positioning:

• Roles change based on ball movement and offensive formation
• Strong safety typically handles "force" responsibility
• Linebacker (Mike) manages cut-back lanes
• Nickel back handles counter, RPO, and boot plays
• Free safety provides "air support" until ball crosses line of scrimmage

Tactical Principles:

• Create one-on-one blocking situations
• Force offensive players into unfavorable matchups
• Use "blast technique" when engaging blockers: land long, be ready to ascend and triangulate
• Adapt formation (e.g., bear front) based on offensive personnel
• Pressure quarterback to disrupt timing

Execution Highlights:

• Defenders maintain gap integrity
• Win at line of scrimmage
• Force quick throws
• Create pressure through strategic positioning
• Emphasize contact and physical play

The system demonstrates flexibility across different defensive looks and offensive formations, allowing defenders to react dynamically to various play types.
