Football Positions Explained: Every Offense, Defense & Special Teams Role

Football positions split into three units on every NFL roster: offense, defense, and special teams, each fielding 11 players with a distinct job. Offense tries to score by running or passing the ball down the field; defense tries to stop them and force a turnover or punt; special teams handles every kick, from kickoffs and punts to field goals. Understanding American football starts with knowing what each of those 33 roster spots is actually asked to do on a given play.

This guide breaks down every position group, explains the one-paragraph job description for each role, and links out to a full breakdown of every individual position so you can go deeper on any one of them.

Offense: The 11 Players Who Move the Ball

The offense’s job is simple to state and hard to execute: gain 10 yards in four downs, or score. Every snap starts with the quarterback position in football, the player who takes the snap and either hands off, throws, or runs. Behind and around him, the running back position in football carries the ball on designed runs and catches passes out of the backfield, while a fullback (when a team uses one) leads the way as a blocker.

Out wide, the wide receiver position explained covers the players who run routes and catch passes downfield — most offenses use two to four receivers per play, split between outside “X” and “Z” receivers and slot receivers who work the middle of the field. The tight end position in football lines up next to the tackle and splits time between blocking like a lineman and catching passes like a receiver, which makes it one of the most versatile jobs on the roster.

None of that works without the offensive line: the center, two guards, and two tackles who snap the ball, protect the quarterback, and open running lanes. They almost never touch the football, but they decide how much time and space every other offensive position gets. For a full breakdown of these five roles, see football offensive positions explained.

Defense: The 11 Players Who Stop It

Defense mirrors offense in structure but not in job description. The defensive line (defensive ends and tackles, plus a nose tackle in some schemes) lines up across from the offensive line to stop the run and rush the passer. Behind them, the linebacker position in football covers players who read the play, fill running lanes, blitz the quarterback, and drop into pass coverage — a middle or inside linebacker often calls the defensive signals, similar to how a quarterback runs the offense.

The defensive backfield, or secondary, is split between the cornerback position in football, who covers receivers man-to-man or in zone near the line of scrimmage, and the safety position in football, who plays deeper as the last line of defense against big pass plays while also helping stop the run. A full position-by-position walkthrough is at football defensive positions explained.

Special Teams: The Third Phase of Football

Special teams handles anything involving a kick, and it decides more games than casual fans realize. The kicker attempts field goals, extra points, and kickoffs. The punter kicks the ball away on fourth down to flip field position. A long snapper delivers a precise, fast snap on punts and kicks, a holder sets the ball for field goal attempts, and return specialists — often a team’s fastest players — try to gain yards on kickoff and punt returns. Blocking for those returners, and covering kicks to stop the other team’s returner, are jobs assigned to reserve players across the offensive and defensive rosters.

Football Positions by Group

Unit	Position	Primary Job
Offense	Quarterback (QB)	Runs the offense, throws or hands off the ball
Offense	Running Back (RB)	Carries the ball, catches passes out of the backfield
Offense	Wide Receiver (WR)	Runs routes, catches passes downfield
Offense	Tight End (TE)	Blocks and catches passes near the line
Offense	Offensive Line (C/G/T)	Blocks to protect the QB and open running lanes
Defense	Defensive Line (DE/DT)	Stops the run, rushes the passer
Defense	Linebacker (LB)	Reads the play, stops runs, covers or blitzes
Defense	Cornerback (CB)	Covers receivers near the line of scrimmage
Defense	Safety (S)	Plays deep, last line against big plays
Special Teams	Kicker (K)	Field goals, extra points, kickoffs
Special Teams	Punter (P)	Punts on fourth down to flip field position
Special Teams	Returner	Returns kickoffs and punts for yardage

How the Positions Work Together

No position operates in isolation. The offense’s personnel and formation dictate which defensive positions get matched up against them — more receivers on the field usually pulls a linebacker off and adds a defensive back, while a heavier run-focused formation invites extra defensive linemen. Coaches on both sides adjust their calls before and after the snap based on which positions are lined up across from them, which is why formations and coverages are their own layer of strategy on top of the individual roles. For how that chess match plays out, see NFL formations and coverages explained.

Special teams then resets the field position for both units after every score, punt, or missed field goal, which is why it counts as a genuine third phase of the game rather than an afterthought between offensive and defensive series.

Frequently Asked Questions

What are the main football positions? They split into offense (quarterback, running back, wide receiver, tight end, offensive line), defense (defensive line, linebackers, cornerbacks, safeties), and special teams (kicker, punter, returners).

How many positions are there in football? There’s no single fixed count since schemes rename and blend roles, but a full roster carries 20-plus distinct named positions across all three units.

What is the hardest football position? Quarterback, because it demands pre-snap reads, in-play processing, and accurate throws under pressure, all within a few seconds.

How many players are on the field per team? Eleven, whether the unit on the field is offense, defense, or special teams.

What’s the difference between a cornerback and a safety? Cornerbacks cover receivers close to the line; safeties play deeper as the last line of defense and help against the run.
