Video Summary
Gap Scheme Fundamentals
- Emphasizes “four eyes on the backers” with double-team blocking at the point of attack
- Describes GF (Guard/Fullback) and GT (Guard/Tackle) blocking schemes
- Guards are taught to kick out defenders rather than log block initially
Position-Specific Responsibilities
- Center/Guard: Execute double-team blocks, working vertically to linebackers
- Tackle: Hinges to protect backside B to C gap when not pulling
- Fullback: Hugs double-teams, looking inside-out for defenders
- Running Back: Aims for inside leg of the guard, progressing from A to B to C gap
Defensive Front Adjustments
- Special “arc release” technique against 3-4 defenses when facing outside linebackers
- Adaptations for different defensive alignments (3-tech, 4-tech, etc.)
Versatility Benefits
- System works for both running and non-running quarterbacks
- Provides more play-action opportunities with fullback/tight end presence
- Allows for “summer rules” (default assignments) that can be adjusted with tags
The coach emphasizes how their blocking scheme has evolved over 15 years to handle multiple fronts and defensive looks while maintaining consistent blocking principles.
