Watch & Learn
The best way to learn football is to watch it explained. Start here.
A clear, concise breakdown of downs, scoring, positions, and the flow of the game — perfect if you've never watched football before.
The Basics
Eight things every fan needs to understand before kickoff.
100 yards long, 53⅓ yards wide — plus two 10-yard end zones. Every 5 yards is marked, with yardage numbers at every 10. Hash marks split the field into thirds vertically. The game starts at each team's 35-yard line on kickoffs.
Every play starts with the center snapping the ball to the QB. The offense sets in formation, the QB reads the defense, then calls signals — "hut!" — to start the play. Nothing happens until the ball is snapped.
The offense gets 4 attempts (downs) to advance 10 yards. Gain 10 yards and the count resets to 1st-and-10. Most teams punt on 4th down rather than risk giving the ball to the opponent in good field position.
A touchdown is worth 6 points — scored by crossing the goal line with the ball. The scoring team then attempts either a kick (1 pt) or a run/pass into the end zone (2 pts). Field goals and safeties round out the ways to score.
Four 15-minute quarters (60 minutes total). The clock stops on incomplete passes, out-of-bounds plays, penalties, and timeouts. Each team gets 3 timeouts per half. A 2-minute warning also stops the clock near the end of each half.
Possession changes via an interception (pass caught by a defender), a fumble recovery (the ball carrier loses the ball and defense recovers), or a turnover on downs (failing to convert on 4th down). All are momentum-shifting events.
The kicking team lines up at their 35-yard line and kicks the ball downfield. The receiving team tries to return it as far as possible. A touchback (ball caught in the end zone and downed) spots the ball at the 25-yard line.
Tied games go to OT. In the NFL, each team gets one possession; if still tied, the next score wins. In college ball, teams alternate from the 25-yard line each OT period. After the 2nd OT, teams must attempt 2-point conversions.
Core Mechanic
The most important concept in football — four chances to move 10 yards.
The offense gains 10+ yards — the chain moves, the count resets to 1st & 10, and the drive continues. This is what the offense is always fighting for.
The ball reaches the end zone on any down. Play stops, the scoring team celebrates, and they attempt the extra point or 2-point conversion.
If the offense can't convert and is too far for a field goal, they punt — deliberately kicking the ball downfield to give the opponent poor field position.
Fail to gain 10 yards in 4 attempts and the defense takes possession at the exact spot the ball was when the play ended. A major momentum swing.
Points
Every way a team can put points on the board.
Roster
11 players per side, each with a defined role and responsibility.
The field general. Calls plays in the huddle, reads defensive coverage pre-snap, and decides to pass, hand off, or scramble. Controls the tempo of the entire offense.
Takes handoffs and finds gaps in the defensive line. Also a weapon in the passing game — screens and check-downs. Must read blocks, break tackles, and protect the football.
The lead blocker ahead of the running back in I-Formation sets. Larger and more physical than a HB. Also used as a short-yardage receiver and in goal-line packages.
Lines up on the outside or in the slot and runs precise routes — cuts, comebacks, post routes, go routes — to get open. Success requires elite speed, sharp route running, and reliable hands.
Hybrid blocker-receiver who lines up next to the offensive tackle. Blocks on run plays, runs routes on passing plays. The modern TE is one of the most versatile and matchup-proof positions in football.
Five players — Center (snaps the ball), two Guards, two Tackles — who create the QB's pocket and open running lanes. The most physically demanding unit. A great OL makes every skill player better.
DTs (Defensive Tackles) and DEs (Defensive Ends) line up against the OL. DTs clog the middle; DEs rush from the edge. A dominant DL disrupts every run and pressures the QB without blitzing.
MLB (Middle), WLB (Weak-side), SLB (Strong-side). They stop the run, blitz the QB, and drop into coverage. The defensive signal-caller, responsible for communicating coverages and adjustments at the line.
Lines up against wide receivers in man or zone coverage. Elite CBs take away an entire side of the field. Their stats are pass breakups and interceptions — often the result of matching up 1-on-1 for entire games.
Two safeties per defense — Free Safety (roams deep, centerfield) and Strong Safety (plays near the box, closer to the line). The last line of defense. If they miss a tackle, it's a touchdown.
Handles kickoffs, field goal attempts, and extra points. A reliable kicker is a 3-point weapon from inside 55 yards. Misses are memorable — kickers live under massive pressure on game-deciding kicks.
Kicks on 4th down when neither a field goal nor going for it makes sense. Great punters pin opponents inside their own 10-yard line — a "coffin corner" punt shifts field position dramatically.
Strategy
How teams line up tells you everything about what they plan to do.
QB lines up 5–7 yards behind center in a "gun" stance. Gives the QB a pre-snap view of the whole defense and extra time to read the field. Standard for obvious passing situations.
QB under center, FB directly behind, RB (HB) 5 yards deep. Classic run formation — the FB leads through the hole as a blocker. Power, misdirection, and play-action play are all built into this set.
4 defensive linemen, 3 linebackers, 4 defensive backs. The most common base defense in football. Strong against the run, with 4-man pressure and linebacker flexibility to blitz or drop into coverage.
3 defensive linemen, 4 linebackers, 4 defensive backs. The NT (nose tackle) absorbs double teams, freeing the OLBs to rush from the edge. Creates disguise — the offense can't tell who's blitzing.

Rule Book
Yellow flag on the play — here's what the referee is calling.
An offensive player moves after lining up and before the snap. The ball is moved back 5 yards. One of the most common penalties in football.
An offensive lineman grabs or wraps a defender's jersey or body to prevent them from making a play. Extremely common — refs choose when to call it.
The offense fails to snap the ball before the 40-second play clock expires. Free timeouts or slow huddles cause this — the ball moves back 5 yards.
A blocker hits a defender in the back or shoulders from behind on a kick return. Common on special teams and kickoff returns.
A defensive player is in or crosses the neutral zone before the snap. The offense gets an automatic 5-yard gain and a free play — the QB can take a shot downfield with no risk.
A defender interferes with a receiver's ability to catch a pass. In the NFL, the penalty is spotted at the foul — potentially giving the offense 40+ yards in one call.
A defender hits the QB after the ball is released or dives on their legs. Protecting the QB is a priority — this penalty also gives the offense an automatic first down.
A late hit, excessive force, or any contact deemed dangerous or unsportsmanlike. Ejection possible for targeting the head. Always an automatic first down.
