Key Differences Between Inside Zone and Duo
- Inside zone uses stacked combos while duo uses hip-to-hip blocking technique
- Running back/QB footwork differs: in inside zone, RB gets to mesh point; in duo, QB brings ball to RB
- Inside zone works better with RPOs and from offset shotgun
- Duo works better from pistol formation and maintains B-gap relationship
Hip-to-Hip Combination Blocking Technique
- Used when anticipating defensive redirects as it keeps offensive linemen square
- Aiming point: play side knee to crotch of defender
- Two player roles in combinations: “drive player” and “lift player”
Technique Specifics
- Drive player: Uses “near-foot lead” or “gallop footwork” with shoulder fit initially
- Lift player: Uses “settle lift footwork” with good posture in squat position rather than lunging
- Both must triangulate the backside foot (90 degrees to contact surface) for leverage
- Proper body posture at contact point is emphasized for power generation
Practice Drills Demonstrated
- Fitted combination drills where players start in the final desired position
- Using pads between blockers to ensure proper hip-to-hip positioning
- Practicing against moving defenders and linebackers
- Hit-and-leave technique for situations with two-gappers or fast-plugging linebackers
