WEAK FAN ZONE PLAY CONCEPT

This coaching presentation breaks down the weak fan zone play, a creative variation of inside zone that changes only one player’s assignment while maintaining all other blocking rules.

CORE PHILOSOPHY

  • Identical coaching points to standard inside zone play
  • Simple tag that changes only one person’s job
  • Different name in the system but same fundamental execution
  • No new coaching required for most players
  • Creative way to get a new play without extra workload

PURPOSE AND STRATEGIC VALUE

The weak fan zone serves as an answer to specific defensive tendencies:

  • Against 50 or 3-4 Defenses: Teams that constantly crash and force quarterback to pull into unblocked waiting defender
  • Against 4-3 with Hanger: When outside linebacker sits in position based on alignment
  • Have the Last Laugh: Provides answers to defensive problems and gets ball into tailback’s hands creatively
  • Change of Pace: Different look without changing most assignments

BLOCKING SCHEME DETAILS

All inside zone rules stay the same except for backside tackle:

  • Running Back: Same footwork, angle, cut read, and aiming point (inside leg of guard) as inside zone
  • Interior Linemen: Standard inside zone combo blocks remain unchanged
  • Backside Tackle: Now fan blocks out on outermost player at linebacker level
  • Read Key Changes: Instead of reading normal inside zone key, now read player head up or inside of tackle
  • Everyone Else: Jobs and assignments completely unchanged

THE READ ELEMENT

Quarterback reads the player who would normally be blocked on inside zone:

  • If Defender Crashes: Turns shoulders to line of scrimmage, quarterback pulls
  • If Defender Sits Flat: Stays in place, give ball to running back
  • Pre-Snap Adjustments: Smart offensive tackles can adjust (example: wide 5-technique, tackle goes underneath to backer)

FILM BREAKDOWN – EXECUTION EXAMPLES

Example 1 – Hard Crash for Touchdown:

  • Defensive tackle crashes hard attacking tailback
  • Left tackle fans out to block player normally waiting for QB
  • Defender handles block poorly (unexpected)
  • Defender actually goes inside, blows contain
  • Quarterback pulls for massive touchdown before halftime

Example 2 – Loosened 3-4 Defense:

  • Outside linebackers playing in space
  • Two-for-two combos on inside remain same
  • Fan outside to block OLB, cut read key loose
  • Hard crash makes easy read for quarterback
  • Simple pull, good job by left tackle in space
  • Nice gain

Example 3 – Quarterback Vertical Running:

  • All coaching points about being vertical back to line of scrimmage apply
  • QB does great job replacing downhill vertically
  • Attacks and draws linebackers into offensive linemen
  • Same coaching points as base inside zone with minor tweak

Example 4 – Defensive Back Eye Discipline:

  • Defensive backs trained all week to support tackling running back
  • Running back sells fake extremely well
  • Corner runs right by play thinking RB has ball
  • Quarterback goes right by him untouched
  • Happens frequently because third-level players not looking for QB (think problem is solved by defensive alignment)

Example 5 – Give Read:

  • Normally four-technique goes out to wide five
  • Smart tackle adjustment – goes underneath to backer instead of fanning way outside
  • QB maintains read on original key
  • Pre-snap width indicates likely give anyway
  • Results in good inside zone run down middle even with fan call

Example 6 – Against Blitz-Heavy 3-4:

  • Team likes to blitz heavily
  • Pick up blitz really well
  • Read key crashes down for tailback
  • Hat on a hat across front
  • Weak side fan blocks outside
  • QB gets nice pull and good run
  • Creates one-on-one battle in space with unprepared third-level player

CRITICAL COACHING POINTS

Running Back Fake Discipline:

  • Running back must carry out fake even without ball
  • Sell is critically important to success of play and entire offense
  • Pulls defensive backs’ eyes into backfield
  • Creates confusion for third-level defenders

Quarterback Mechanics on Pulls:

  • Be vertical back to line of scrimmage
  • Replace downhill vertically
  • Attack and draw linebackers into offensive linemen
  • Get upfield quickly
  • Same fundamentals as base inside zone

Why It Works:

  • Blocks the player who normally would have quarterback
  • Makes third-level players responsible for QB
  • Something they haven’t practiced that week
  • 50 and 3-4 systems tell players all week “you have the quarterback”
  • Now those players aren’t ready when QB actually has ball

INSTALLATION SIMPLICITY

The coach emphasizes minimal installation burden:

  • Only affects one player (backside tackle)
  • Everyone else runs standard inside zone
  • Simple understanding: when you hear this tag, one job changes
  • That one person must execute properly
  • No extra practice time needed for most of roster

ONE-ON-ONE BATTLES IN SPACE

The play is designed to create favorable matchups:

  • Get quarterback pulling into space
  • Third-level defender not accustomed to tackling QB
  • Pick up extra yards because defender isn’t prepared
  • Force defensive backs to make plays they haven’t practiced

The presentation demonstrates how a single blocking adjustment can create an entirely new play that keeps the same coaching points, requires minimal extra practice time, and provides answers to specific defensive tendencies – particularly against 50 and 3-4 fronts that crash hard to stop inside zone.
