1. Defensive Front Positioning Principles:

• Set the front to the tight end's side
• If no tight end, set to the field side
• If trips formation, set away from trips
• Goal is to position defenders where the offense is likely to run the football

2. Alignment Specifics:

• Defensive line uses techniques like 9, 3, shade, and 5 positions
• Linebackers typically use 50 and 10 techniques
• Safeties and corners adjust based on offensive personnel and receiver positioning
• Defensive positioning changes with different offensive formations (21, 11, 10 personnel, twins, doubles)

3. Strategic Considerations:

• Defensive positioning is about anticipating running lanes
• Flexibility to adapt to different offensive sets
• Understanding run fits and gap responsibilities is crucial
• Potential to substitute players (like bringing in a nickel back) based on offensive formation
