One-gap and two-gap defense are built around the same objective: control the run game, account for every gap and keep the front connected. The difference is how each defender is asked to accomplish it
In a one-gap structure, the defender is responsible for attacking and controlling one assigned gap. The emphasis is on get-off, first-step quickness, leverage, hand usage and disruption. Penetration can create negative plays, but it only matters if the defender maintains gap integrity and does not run himself past the football
In a two-gap structure, the defender is asked to control the blocker in front of him while staying square enough to defend either adjacent gap once the run declares. That requires strength, length, heavy hands, extension, vision, patience and the ability to shed without guessing too early
From a coaching perspective, the technique changes the way the entire front fits together. One-gap concepts can allow defenders to attack more aggressively, while two-gap concepts can help control blockers and create cleaner pictures for linebackers behind the front
From a scouting perspective, I want to understand what the player is actually being asked to do before judging the result. A one-gap player may win with explosiveness, lateral quickness and penetration, while a two-gap player may provide value through anchor, block control, leverage and the ability to keep second-level defenders clean
The biggest takeaway is that alignment does not automatically equal assignment. A head-up defender is not always two-gapping, and an offset defender is not always one-gapping. The call and the responsibility tell the full story
Lane Kiffin hired Eric Wolford to be his offensive line coach at #LSU.
Here’s Wolford working with some of the younger linemen. He was extremely thorough during practice.
LSU OL Half Line Power/Counter Drills: frontside group works down blocks & double teams while the backside group works pulls, back blocks, & hinges
Every inside zone block has a moment of truth.
It's the instant the running back commits and the defender has to make a choice:
Protect himself... or fight to make the tackle.
John Benton teaches offensive linemen how to win that moment by creating vertical force, finishing through contact, and giving the back extra yards even if the defender stays in the play.

O-Line Gap Combos Drill
- Utilize gallop footwork to gain ground toward the defender.
- Drive vertically and downhill rather than stepping away or trying to reach the perimeter.
- Avoid leaning at the waist; maintain an upright posture to keep the shoulder, hip, and knee engaged for maximum power.
- Apply a U-turn technique when coming off a block to a linebacker to use the defender's momentum to open a crease.
- Set the aiming point for the offensive lineman as the defender's backside number when coming off a block.
- Focus on getting the hip and knee into the block rather than just relying on the upper body.

Great offensive line coaches don’t start with schemes.
They start with people, teaching, and clarity.
🧵
In this presentation from the 2024 C.O.O.L. Clinic, @coachhallett walks through the coaching influences that shaped how he teaches the game—especially the Mount Union lineage and the belief that coaching is teaching.
Personnel first.
Formations second.
Plays last.
It’s a simple filter, but it shows up in everything he does—from install structure to daily drill work.
Stick with this thread. You’ll definitely steal the drill in Post 3.

O-Line Strain Drill
- The strain drill begins with the offensive lineman in a proper fit position with elbows bent.
- All drills should start with the offensive lineman's feet on fire rather than from a static position.
- On the ready command, the player's feet must move, and on the go command, the hips should be the first thing to activate the drive movement.
- During the drill, the defensive player maintains outside leverage on the shoulder pads and attempts to pull the lineman off the line.
- Offensive linemen must focus on maintaining fast feet, staying square, and keeping a strong position with their elbows squeezed.
- This drill is designed to train players for the finish phase of blocking a defensive lineman or for second-level strikes on linebackers.
