Lecture on Installing Duo with Coach Ryan Swingle

Introduction to Duo

• What is Duo?
  • Downhill, fast-hitting gap scheme
  • Double team-based play
  • No puller involved
  • Aim is to get vertical displacement of down linemen
  • Move the line of scrimmage downfield to the defense
  • Deliver first-level defenders into the laps of linebackers

Key Characteristics of Duo

• Comparison to Inside Zone:
  • Similar to gap schemes like Power and Counter
  • Both sides block like in gap schemes but no pulling
  • High-level overview: a double team and vertical displacement
  • Run ideally from under center or pistol position

Running Back Reads in Duo

• Anchor Key and Peripheral Key:
  • Anchor Key: Mike Linebacker
  • Peripheral Key: Will Linebacker
  • Aim to run from under center or pistol to get RB downhill
  • Sidecar position is less ideal
  • Running backs should be at 7.5 yards depth

Techniques and Aiming Points

• Running Back Aiming Points:
  • Under Center: Heels at 7.5 yards
  • Pistol: 2.5 yards behind QB, still at 7.5 yards
  • Gun: Toes to the heels of QB, crotch splits outside leg of play side guard
  • Drop step footwork, aiming point outside hip of play side guard

Blocking Calls and Line Combinations

• Terminology for Blocking:
  • Ace: Center and play side guard double team to Mike
  • Doom: Play side tackle and guard double team to Mike
  • Tram: Play side tackle and tight end double team to Mike
  • Quad: Tight end or wing/receiver in condensed split double team
  • Lane: One-on-one block on front side (e.g., guard vs. 2i)
  • Sig: Center and back side guard double team to backside linebacker
  • Secure: Center securing A gap to minus one linebacker (Will)
  • Fan: Abort double teams to walked-up linebacker threatening off the edge

Diagramming Duo Plays

• Versus Different Fronts:
  • Five-man front
  • Four-man front
  • Three-man front
  • Use of line calls like Ace, Doom, Tram, Quad, and Lane

Reading Defenders

• Running Back's Primary Visual Anchor:
  • Eyes locked on Mike Linebacker
  • Peripheral key used if Mike moves outside
  • Bend read outside gap, cram inside gap, or bounce out wide

Blocking Adjustments

• Working Against Movements and Stunts:
  • Center/Gaurd adjust to 2i, 3-techniques, and tilted shades
  • Gallop technique for double teams: Vertical engagement
  • Reading slants and adjustments dynamically

Examples and Film Analysis

• NFL and College Footage:
  • Examples from Rams’ Super Bowl run
  • Hamilton College footage for various formations and blocking schemes
  • Analyzing successful and unsuccessful plays
