Installing the Air Force Base 3-4 Defense

Tim DeRuyterAir Force Academy

• Advantages of Basing out of a 3-4

• Personnel– * Get Better Athletes on Field– * Easier to Recruit LB’s than DL’s

• Multiplicity of Fronts, Coverages, Pressures– * Any of 4 LB’S Can easily be in rush– * Offenses must prepare to block all or none of them– * Easy to Disguise

• Different– * Offenses have 1 week to prepare– * Where is Shade/ 3 Tech?– * Simplified Gameplans 2

• Installing a Base 3-4• First Questions:

– * Who / Where is 4th Rusher?

– * How does the coverage tie in?

3

• Installing a Base 3-4• Where Can we Set 4th Rusher:

– * OPEN 63 / CLOSED 36– * BENCH PURPLE / FIELD RED– * MIKE / WILL BLUE– * STRONG RED / WEAK PURPLE– * TILT

4

• Installing a Base 3-4• OPEN 63

– * 4TH Rusher from “Open” Side– * Coverage is “Double Digit” (Could play man)

– - ¼, ¼, ½ vs PRO Sets (Cover 6)– - Cover 3 vs SLOT Sets– - Change of Strength Motion Changes Coverage

- Front does not Change
