Weaknesses

• Tackles had to be multiple– Play 3 tech and 5 tech

• Rovers had to be multiple– Play OB and DE

• Over front (5) was more complicated if teams were multiple

• Played under 80% of time

Bullet Defensive Principals

• Front four multiple (Stem and Stunt)• Very simple/ Gap control

– No confused players = faster players– Easy to adjust to multiple offenses

• Strong side and weak side players– Players get a great deal of reps in familiar

technique• Bend don’t break – not a huge blitzing

team• Zone coverage

Bullet Defense Positions

• Strong Side– Tackle: Inside lineman– End: Outside lineman– Mike: Inside linebacker– Sam: Outside linebacker

• Defensive backs do not have strength– Right corner, Left corner, Free safety

• Weak Side– Nose: Inside

Lineman– Anchor: Outside

lineman– Will: Inside

linebacker– Rover: Outside

Bounce to Under - Then Tag

Other Fronts and Stunts

• Pinch – Tackle and Nose both play shades

• Stack Pinch – Tackle and Nose start in 2 techs and pinch to “A” Gap

• Over Head – End plays 8 technique• Strong Tag – Only Tackle Tags • Weak Tag – Only Nose Tags

Blitzing

• Blitz linebackers by names of linebacker– If we want to send Mike we call Mike– Linebacker(s) called to go blitz their gap.– Stunts are created by stunts previously

talked about – Bounce, Tag, X, etc.– Possibilities are endless.– Limit to a small number each week

depending on game plan.

Examples of Blitzes

• Over Tag Mike • Under Tag X Will Sam

Pass Coverage – Cover 3

• Cover receivers in area • Don’t cover green grass• Communication is key

• Out (Quick Out – within 5 yards)• Under (Quick In – Routes under ILB)• Dig (Deep in – 7+ yards)• Dog (Deep Out – 7 + yards)• Cross (Receiver crosses 1 deep zone into

another)• Vert – Vertical Route

Adjustments to Spread

• Do we need to adjust?– Is a team in spread to run or throw?– Do we need another safety in the game?

• Is 4 verticals a real threat?• Where are they throwing the ball?

• Rover will move back and play safety.– 4-3 Look

• Vs Doubles (Cover 2 Read)• Vs Trips (¼ - ¼ - ½, with Will playing pass

strength)
