American football (NFL)

There are 11 players per side. The offense has at least 7 players on the line of scrimmage: five offensive linemen (center, two guards, and two offensive tackles) and two eligible receivers. There are four backfield players: a quarterback, full back, half back or running back RB, and a wide receiver WR. The quarterback can choose to run or pass. The five offensive linemen (numbers 50 to 79) are not eligible receivers until an eligible receiver or defense touches the ball, and cannot advance more than two yards. A tight end is on the offensive line but is an eligible receiver. Linemen start in the three-point stance to increase speed. Only one offensive player (a WR or RB) can be in motion at the snap, and cannot be moving forward.
The defense contains four defensive linemen and three linebackers (4-3), two cornerbacks, and two safeties. The defensive line consists of 1-2 defensive tackles (the nose tackle if just 1) and two defensive ends. Linebackers are middle and outer (OLB), and target tight ends and running backs. The goal is to tackle the ball carrier (a sack for the quarterback). A blitz involves extra players attacking the quarterback.
There are four 15-minute quarters. Edge rushers are on the outside of the defensive line.
The winner of the coin toss decides to receive, defend, or defer (let the other team choose). There is also a kickoff after each score, where the kick return will receive the ball and run as far as possible.
The offense has four downs to gain 10 yards. They are called as nth down and m yards to go. A turnover on downs allows the other team to take over at that spot. On the fourth down, teams may choose to score a field goal for 3 points, or punt the ball. Most drives end with a punt, since a 4th-and-8 has 34% success rate. The returning team can muff the punt if they touch the ball but the other team steals it. A turnover also happens on an interception or fumble, where the defense lands on the ball before it goes out of bounds.
A down starts with a snap or free kick. The line of scrimmage cannot be contested, meaning neither team can touch the neutral zone, except for the center or long snapper.
A touchdown is worth 6 points, and is followed by the Point After Attempt, where teams can kick an extra point (same as a field goal) or run a two-point conversion from the two-yard line. A safety is when a defense tackles an offensive player in their own end zone.
The special teams handle kick attempts (extra point or field goal attempt/block) and punts (kickoff or punt kick/return). The long snapper is a center who snaps 8 yards for field goals and 14 yards for punts.
Zone defense: Cover 0 is pure man coverage. Cover 1 has one safety for deep defense. Cover 2 has free safety and strong safety for deep defense. Tampa 2 is Cover 2 with the middle linebacker covering medium to deep middle. Cover 3 has two corners and free safety for deep defense, while the strong safety plays as a linebacker. Cover 4 is a prevent defense to run out the clock, allowing short gains and preventing long passes.
A sweep is when a running back runs parallel and then runs up through the alley. A jet sweep is when the wide receiver runs with the ball.
