Base 3-4 Okie

Standard 3-4 alignment with a nose over center and two ends in 5-techniques plus four linebackers.

Concept: Nose two-gaps the A-gaps, ends control the B/C gaps, and inside backers fill the open A-gaps.

Same play, more layers as they age up — teach it once and build on it every season for a consistent program.

  1. 6UIntroduce: Line up right and own your gap — win with alignment, pad level, and pursuit to the ball.
  2. 8UAttack blocks: Add get-off and block destruction so the front controls the line of scrimmage.
  3. 10UAdd coverage: Teach the coverage drops behind the front and read run vs. pass.

How to teach it

  • 1The nose two-gaps the center controlling both A-gaps; the ends two-gap the B/C gaps.
  • 2Inside backers read the guards and fill the open A-gaps the nose frees up.
  • 3Outside backers set the edges and are the contain/force players.

Common mistakes to fix

  • !Nose getting washed out of an A-gap; fix by staying square with hands inside on the center.
  • !Inside backers filling the wrong A-gap; fix by reading the guard and pressing the open gap downhill.
