4-3 Over
Strong-side shade, 1-tech nose
- Front
- Linebacker
The 4-3 Over shifts the defensive line strength toward the offense's strong side. The 3-technique tackle aligns to the strong side of the formation, while the 1-technique nose shades the weak A-gap. The MIKE fits the strong-side A/B gap on most flow reads while reading through the weak A; the 1-tech occupies the center to keep him clean. It remains one of the most versatile and balanced fronts in football.

Tom Landry's Dallas Cowboys popularized the 4-3 alignment in the 1960s, establishing it as the NFL's default front for decades. The Over shade became the standard way to align a 4-3 toward formation strength.
Run game vs the 4-3 Over
10 RATED- Inside ZoneEdge
Zone blocking creates lateral movement that overwhelms the 4-3 over gaps; the playside DE is sealed by the tackle's zone step.Show reasoning
Conflict defender. Playside defensive end (sealed by the tackle)
Why the offense wins. Zone blocking creates lateral movement that overwhelms the 4-3 over gaps; the playside DE is sealed by the tackle's zone step.
Key adjustment. Spill the zone with penetration from the 3-technique and force the back to bounce.
- Outside ZoneEdge
Stretch creates lateral movement that outflanks the 4-3 over front; the back reads the C-gap and bends back inside if needed.Show reasoning
Conflict defender. Playside defensive end (reach block)
Why the offense wins. Stretch creates lateral movement that outflanks the 4-3 over front; the back reads the C-gap and bends back inside if needed.
Key adjustment. Set the edge with the DE and have the WILL scrape over the top to the outside.
- PowerEdge
Guard pull creates a numbers advantage at the point of attack; the FB/TE kicks out the DE and the pulling guard leads through the hole.Show reasoning
Conflict defender. Defensive end (kick-out block)
Why the offense wins. Guard pull creates a numbers advantage at the point of attack; the FB/TE kicks out the DE and the pulling guard leads through the hole.
Key adjustment. DE must wrong-arm the kick-out block to spill the play outside.
- CounterEdge
Counter action freezes the backside linebackers while the guard and tackle pull to create a numbers advantage at the point of attack.Show reasoning
Conflict defender. WILL linebacker (playside gap)
Why the offense wins. Counter action freezes the backside linebackers while the guard and tackle pull to create a numbers advantage at the point of attack.
Key adjustment. WILL must read the pulling linemen, not the back, and scrape over the top to the ball.
- DuoEdge
Vertical double-teams on the DTs create massive displacement; the back reads the MIKE and runs to daylight.Show reasoning
Conflict defender. MIKE linebacker (A-gap)
Why the offense wins. Vertical double-teams on the DTs create massive displacement; the back reads the MIKE and runs to daylight.
Key adjustment. MIKE must attack the A-gap aggressively and not let the double-team reach him.
- TrapEdge
The guard pulls to trap the first down lineman past the center on the playside; his upfield charge is used against him as the guard kicks him out.Show reasoning
Conflict defender. Shade nose (trap target, first lineman past the center)
Why the offense wins. The guard pulls to trap the first down lineman past the center on the playside; his upfield charge is used against him as the guard kicks him out.
Key adjustment. Have the shade nose read the down block and squeeze flat instead of penetrating.
- DrawEdge
Pass-rushing DTs penetrate upfield and open running lanes behind them; the draw uses their aggression against them.Show reasoning
Conflict defender. 3-technique defensive tackle
Why the offense wins. Pass-rushing DTs penetrate upfield and open running lanes behind them; the draw uses their aggression against them.
Key adjustment. DTs must stay square in their gap and read run before committing to pass rush.
- Zone ReadEdge
The read key DE is unblocked and put in conflict: if he crashes, the QB keeps; if he stays home, the RB gets the ball.Show reasoning
Conflict defender. Backside defensive end (read key)
Why the offense wins. The read key DE is unblocked and put in conflict: if he crashes, the QB keeps; if he stays home, the RB gets the ball.
Key adjustment. Assign a spy or scrape exchange where the LB fills for the crashing DE.
- Toss/SweepToss-up
The over front DE can set the edge and force the toss back inside.Show reasoning
Conflict defender. Defensive end (C-gap)
Why the offense wins. Pulling guards create a numbers advantage on the edge.
Why the defense wins. The over front DE can set the edge and force the toss back inside.
Key adjustment. Have the end set the edge and the WILL scrape over the top to the toss.
- Jet SweepToss-up
The over front DE can set the edge with good technique and force a cutback.Show reasoning
Conflict defender. Playside defensive end (edge)
Why the offense wins. Jet motion outruns the pursuit angle of the over front DE.
Why the defense wins. The over front DE can set the edge with good technique and force a cutback.
Key adjustment. Have the end set the edge and the WILL scrape to the sweep.
