The Positions · By Coach Jay Freeman
Line Positions Explained
Every job on the line — what it does, the traits that matter, and how it’s coached. Five up front on offense, the front on defense.
The offensive line
Center
The center snaps the ball and runs the offensive line. He's the smartest guy up front — the one who sets the protection and makes the calls.

The guards are the power of the offensive line — interior maulers who drive the run game, pull to lead on sweeps, and wall off the inside in pass pro.
Read the position →O-Line · OTOffensive Tackle
The tackles guard the edges — and the left tackle guards the quarterback's blindside. They're the tallest, longest, most athletic linemen, built to handle the best pass rushers in the game.

Defensive End
The defensive ends play the edges of the defensive line — setting the edge against the run and getting after the quarterback. What the job looks like depends on the scheme.
Read the position →D-Line · DTDefensive Tackle
Defensive tackles play the interior of the defensive line — stuffing the run up the middle and collapsing the pocket from the inside. The 3-technique is the disruptor.
Read the position →D-Line · NTNose Tackle
The nose tackle lines up over the center and does the most thankless job in football — eating double-teams so everyone behind him can run free. He's the biggest man on the field.

"EDGE" is the modern label for the primary edge pass rusher — the player whose job is to get to the quarterback off the edge, whether his official title is defensive end or outside linebacker.

- What are the positions on the offensive line?
- The offensive line has five positions: the center (snaps the ball and makes the line calls), two guards (interior power blockers who pull and double-team), and two tackles (edge protectors, with the left tackle guarding the blindside). Left to right it reads LT, LG, C, RG, RT.
- What are the positions on the defensive line?
- The defensive line is made up of defensive ends on the edges and defensive tackles inside, with a nose tackle over the center in odd fronts. The primary edge pass rusher is often grouped as an "EDGE" — a 4-3 defensive end or a 3-4 outside linebacker. Alignments like the 3-technique (DT on the guard) and 0/1-technique (nose over the center) describe where they line up.
- Which offensive line position is the most important?
- It depends on what you value. The left tackle is historically the most valued and highest-paid because he protects a right-handed quarterback's blindside. The center is the most mentally demanding — he runs the line. Both are critical; the line only works when all five play as one.
- What is the difference between a defensive tackle and a nose tackle?
- A nose tackle lines up over the center (0/1-technique), two-gaps, and anchors against double-teams — usually the biggest defender. A defensive tackle (often a 3-technique on the guard) is more of a penetrating, disruptive interior player. The nose is the anchor; the 3-tech is the disruptor.
