Core Principles of the Fangio Defensive System

To define the Fangio system, identify its foundational components as documented in professional coaching clinics.

Fangio defenses prioritize split-safety structures.
Two-high safety alignments serve as the default framework.
This structure limits vertical route efficiency and controls deep passing lanes.
Zone-match principles allow defenders to transition between zone and man responsibilities.

Pressure design relies on simulated looks.
Fangio deploys four-man rushes combined with linebacker or secondary rotation.
This approach creates uncertainty without sacrificing coverage integrity.
Analytics reports associate these tactics with reduced quarterback efficiency under pressure.

Key Structural Elements

• Control leverage to protect deep zones

• Rotate safeties after the snap

• Disguise coverage pre-snap

• Anchor run fits with disciplined fronts

• Simulate pressure without heavy blitz rates
