The Football Glossary

blitz

Sending more than four rushers, accepting thinner coverage behind it to force a fast, uncomfortable throw.

block in the back

Contact from behind against a player who isn't the ballcarrier. The most-thrown flag on returns and perimeter runs — the fix is positioning: block only what you can see the front of.

boundary

The short side of the field when the ball is on a hash. Its opposite is the field (wide) side.

box

The area near the line of scrimmage where the linemen and linebackers operate — roughly tackle to tackle, eight yards deep.

conflict defender

A defender assigned two responsibilities that one play can attack at once — run fit and pass coverage. Good offenses pick out this player and make him wrong either way.

constraint play

A play run not because it is the best play, but to punish the defense for cheating against your base play. The screen that punishes a hard pass rush; the keeper that punishes a crashing end.

corner

A deep route that breaks toward the pylon, away from the middle. The route that sits over a Cover 2 cornerback's head.

Cover 2

Two deep safeties splitting the deep field in half; five defenders underneath. Strong against short outside throws, stressed deep down the middle and on the sideline behind the corners.

Cover 3

Three deep defenders each taking a third; four underneath. Sound against deep balls, stressed by four vertical receivers and quick outs.

defensive line

The defenders in a stance on the line of scrimmage: ends on the edges, tackles inside, a nose over the center when there is one.

dig

An in route: ten to fifteen yards, then a square break across the field. Works the window behind the linebackers in zone.

down

One attempt to advance the ball. The offense gets four downs to gain ten yards; succeed and the count resets.

fade

A go route along the sideline, thrown high and outside where only the receiver can reach it. The red-zone jump ball.

field

The wide side of the field when the ball is on a hash — at high school hashes, about thirty-five yards of grass. Defenses rotate coverage toward the field because space is where speed plays.

fire zone

A pressure that sends five rushers but keeps zone coverage behind it — usually three deep, three under — often by dropping a lineman into coverage.

four-minute offense

The opposite art: keeping the ball on the ground and the clock moving to end the game with a lead.

free-blocking zone

A small box around the ball at the snap where certain otherwise-illegal blocks are permitted at some levels. Outside it, restrictions apply.

gap

The space between two offensive linemen. Defenses assign one defender to each gap so every running lane is accounted for.

gap scheme

Linemen block down away from the play and a puller leads through the hole. Creates new gaps at the point of attack by force.

hard count

A quarterback's snap-count cadence that tries to draw a defender across the line early, or reveal a blitz by making the defense flinch.

hash marks

The two rows of small lines marking where the ball is spotted between plays. Their width apart differs by level, and that difference quietly drives strategy.

hidden yardage

Field position gained or lost outside offense and defense — returns, coverage, touchbacks, penalties on kicks. It rarely makes highlights and often decides games.

hitch

A short route — five to eight yards — that turns back toward the quarterback. The safest throw in the book against a soft corner.

holding

Grabbing or hooking an opponent to restrict him. On offense it costs 10 yards; it happens most when a blocker has lost position and grabs instead of moving his feet.

hot route

A short, quick route thrown when the defense sends more rushers than the protection can block.

ineligible man downfield

A lineman too far past the line of scrimmage before a forward pass is thrown. The allowed distance differs by level (roughly 3 yards at high school and college, 1 at pro) — a rule that quietly shapes which RPOs are viable where.

kickoff

The kick that starts each half and follows every score. The return team's first possession starts wherever its runner is stopped — or at a set line in leagues that have removed the play.

leverage

Which side of an opponent a player positions himself on. A defender with inside leverage is telling you the ball should be forced outside.

line of scrimmage

The imaginary line across the field where the ball sits before the snap. Neither team may cross it before the play starts.

man coverage

Each defender is responsible for a specific receiver wherever he goes.

mesh point

The moment the quarterback and running back come together on a handoff or read play. Where the decision happens.

Mike

The middle linebacker — the defense's signal-caller, and the man the quarterback points to when he sets the protection ('the Mike').

neutral zone

The length of the ball between the two lines at the snap. Nobody but the center may be in it before the ball moves. Created in 1906 to stop the shoving matches that started before plays did.

nickel

A fifth defensive back, traded in for a linebacker against three-receiver sets. A sixth is the dime.

offensive line

The five in a row who cannot catch a forward pass: center, two guards, two tackles. They decide most plays and touch the ball on none of them.

offensive pass interference

A receiver initiating contact that impedes a defender before the ball arrives — including setting a stationary 'pick.' Crossing routes are legal traffic; stopping to obstruct is the flag.

pattern matching

A hybrid: defenders start in zones, then lock onto receivers man-to-man based on the routes that show up. Looks like zone, plays like man.

personnel package

The mix of running backs, tight ends, and receivers on the field, usually named by two digits: 11 personnel = 1 back, 1 tight end (and therefore 3 receivers).

play-action

A pass dressed up as a run. Punishes defenders whose eyes commit to run keys.

possession

One team's turn with the ball, from kickoff or takeover until it scores, punts, turns it over, fails on fourth down or the half ends. Possessions, not yards, are the game's currency.

post

A deep route that angles toward the goalposts — into the hole between two deep safeties, or past a single deep safety's shoulder.

pre-snap read

Everything the quarterback learns before the ball moves: the shell, the leverage of corners, the linebackers' depth, who is over the center.

progression

The quarterback's ordered list of receivers to look at on a pass play. First read, second read, checkdown.

pulling

A lineman leaving his spot at the snap to run to a different gap and block there. The signature of gap-scheme runs.

punt

Kicking the ball away on fourth down to hand the other team a possession farther from your goal line. Not surrender — a trade of this possession for field position on the next one.

read option

A run play in which one defender is deliberately left unblocked and 'read' — if he attacks the back, the quarterback keeps; if he stays home, the quarterback gives.

rotation

Safeties moving from their pre-snap picture into their real coverage after the snap. Late rotation is disguise.

RPO

Run-pass option. The line blocks a run; the quarterback reads one defender and either hands off or throws based on what that defender does.

screen

Letting the pass rush come, then throwing behind it to a receiver with blockers in front. A play, not a route — and the answer to a defense that rushes too hard.

seam

A vertical route up the hash marks, into the soft spot between deep zones. Four Verticals is built on two of them.

shell

The arrangement of the deep defenders before the snap — one safety deep, two safeties deep, or none. The first thing a quarterback reads.

single wing

The dominant offense of the early 1900s: an unbalanced line and a direct snap to a back who could run, pass or kick. Pop Warner's system; its misdirection survives in the wing-T and the wildcat.

slant

A quick inside break after two or three steps. Beats press man and attacks the space behind linebackers.

special teams

Every play involving a kick: kickoffs, punts, field goals, extra points, and their returns.

T formation

Quarterback under center, three backs behind him in a T. Revived in 1940 with a man in motion, it made the handoff fake and the play-action pass the core of modern offense.

targeting

Forcible contact to an opponent's head or neck area, or leading with the crown of the helmet. Penalized at every level; at some levels it carries ejection.

two-minute drill

The offense's hurry-up operation to score before a half ends: clock stops, sideline throws, timeout math.

two-platoon

Separate offensive and defensive units, made possible by free substitution. Before it, the same eleven played both ways — as they still often do at youth and high school.

wheel

A back or slot who starts toward the flat, then turns up the sideline. Punishes a linebacker who relaxed.

zone blocking

Linemen block an area moving in one direction, working in tandem, rather than a specific man. The back reads the movement and picks the lane.

zone coverage

Each defender is responsible for an area; receivers are passed between zones.
