The Basics: What Is the NFL?
The National Football League (NFL) is the top professional American football league in the world, founded in 1920. It consists of 32 teams split into two conferences — the AFC (American Football Conference) and the NFC (National Football Conference). Each conference has 16 teams divided into four divisions of four teams each.
The goal of each team is to advance an oval-shaped ball into the opposing team's end zone to score points. The team with the most points at the end of the game wins. It sounds simple — and the basic idea really is — but the strategy and rules make the NFL one of the most tactically rich sports in the world.
The Field
An NFL field is 100 yards long and 53.3 yards wide, with a 10-yard end zone at each end (the scoring areas). There are lines every 5 yards, with numbers marking every 10 yards. The 50-yard line is the center of the field. The two "goalposts" stand at the back of each end zone.
Each team defends one end zone and attacks the other. Teams switch sides at halftime.
How Scoring Works
There are four ways to score in NFL football:
| Method | Points | How It Happens |
|---|---|---|
| Touchdown (TD) | 6 | A player carries or catches the ball in the opponent's end zone. |
| Extra Point (PAT) | 1 | A kick through the goalposts after a touchdown. |
| Two-Point Conversion | 2 | Running or passing into the end zone after a TD instead of kicking. |
| Field Goal (FG) | 3 | A placekick through the upright goalposts from the field of play. |
| Safety | 2 | Tackling the opposing ball carrier in their own end zone. |
How a Game Is Played
NFL games consist of four 15-minute quarters for a total of 60 minutes of official play. The clock stops for incomplete passes, out-of-bounds plays, and penalties, so a typical NFL game takes about 3 hours to watch.
The game is structured around downs. The offense (the team with the ball) has 4 attempts (downs) to advance the ball 10 yards. If they succeed, they earn a new set of 4 downs (called a "first down"). If they fail after 4 downs, the opposing team gets the ball.
Most teams will punt (kick the ball away) on 4th down if they don't think they can make 10 yards, rather than risking giving the ball to the other team in good field position. Alternatively, if they're close enough to the goalposts, they may attempt a field goal.
Every offensive play starts with the snap — the center (an offensive lineman) hands or throws the ball backward to the quarterback between their legs. This signals the start of the play. Before the snap, both teams line up facing each other at the line of scrimmage (where the last play ended).
Offense vs Defense
Each NFL team has three separate units: offense (when your team has the ball), defense (when the opposing team has the ball), and special teams (kicks, punts, and field goal attempts). Different players make up each unit — most players only play on one side of the ball.
Key Positions to Know
With 22 players on the field at once (11 per team), positions can seem overwhelming. Here are the most important ones to understand:
The NFL Season
The NFL season follows a structured annual calendar:
- Training Camp (July–August): Teams prepare, compete for roster spots, and install new schemes. 53-man rosters are finalized.
- Preseason (August): 3 games that don't count in the standings. Used to evaluate players, especially backups.
- Regular Season (September–January): Each team plays 17 games over 18 weeks (one bye week). Teams earn playoff spots based on their record.
- Playoffs (January–February): 14 teams compete in a single-elimination tournament.
- Super Bowl (February): The NFL Championship Game. One of the most-watched TV events in America every year.
The Playoffs & Super Bowl
The 14 teams that qualify for the playoffs consist of the division winner (best record) from all 8 divisions plus 3 wild card teams from each conference (the next-best records). The team with the best record in each conference gets a first-round bye (they skip the first week and go straight to the second round).
The playoffs consist of four rounds:
- Wild Card Weekend — 6 games (seeds 3–6 in each conference)
- Divisional Round — 4 games
- Conference Championships — 2 games (AFC Championship + NFC Championship)
- Super Bowl — The AFC champion vs the NFC champion. This game is played at a neutral site and is one of the biggest sporting events on earth.
The Super Bowl winner receives the Vince Lombardi Trophy, named after legendary Green Bay Packers coach Vince Lombardi. It's made of sterling silver and weighs about 7 pounds. The Kansas City Chiefs have won it four times in the last six years (most recently Super Bowl LVIII in February 2024).
Important Rules
Penalties
Violations of the rules result in penalties — yardage losses or gains for the affected team. Common penalties include:
- Holding (10 yards) — An offensive player grabs a defender illegally.
- Pass Interference (spot of the foul) — A defender illegally contacts a receiver before the ball arrives.
- Offsides/False Start (5 yards) — A player jumps before or across the line of scrimmage at the snap.
- Personal Foul (15 yards) — Illegal hits, targeting, or unnecessary roughness.
Challenges and Replay
NFL coaches have the ability to challenge certain calls on the field. If the replay shows the ruling was wrong, the call is reversed. Each team gets 2 challenges per game, plus a potential third if both earlier challenges were successful. The NFL also has an automatic replay review system for turnovers, touchdowns, and the final 2 minutes of each half.
