The general makeup of the offense can vary play-to-play, here are some of the positions that may be used:\n• The Quarterback\n• The Center\n• Two guards\n• Two tackles\n• Two/four wide receivers\n• The running back\n• The Fullback\n• One of two tight ends\n\n* The Defense: \nThe job of the defense is to stop the offense. The 11 men on the defensive team all work together to keep the offense from advancing toward the defense's end zone. The general makeup of the defense can vary play-to-play, here are some of the positions that may be used:\n• Linebackers\n• Defensive ends\n• Cornerbacks\n• Strong Safety\n• Free safety\n• Nose, or defensive, tackle\n\n**The Playing field:**\n\nThe field is 100 yards long and 53 yards wide with white markings on the field called yard markers to help keep track of the ball. The end-zone (or goal) is an additional 10 yards at each end of the field where each time try and score.\n\n**Timing**\n\nNFL games are divided into four 15-minute quarters, separated by a 12-minute break at halftime. \n\nThere are also 2-minute breaks at the end of the first and third quarters as teams change ends of the field after every 15 minutes of play. At the end of the first and third quarters, the team with the ball retains possession heading into the following quarter. That is not the case before halftime. The second half starts with a kickoff in the same way as the game began in the first quarter.\n\nIf a game is tied at the end of regulation, a 15-minute overtime period will be played. In the NFL, this is sudden death and the first team to score wins. Possession is determined before the period begins by a coin toss.\n\n**Kickoffs**\n\nNFL games start with a kickoff. \n\nThe ball is placed on a kicking tee at the defense’s 35-yard line, and a kicker kicks the ball to the opposition to take possession. \n\nA kick returner can catch and advance the ball. Where the player is stopped is the point from which the offense will begin their offensive drive.\n\nIf the ball is caught in their own end zone, the kick returner can either run the ball out of the end zone, or kneel in the end zone to signal a touchback to stop the play. The ball is then placed on the 25-yard line, where the offense begins play.\n\n[Further rules](https://operations.nfl.com/the-rules/nfl-video-rulebook/kickoff-rules/)\n\n**Offensive possession**\n\n* Running Plays\n\nA running play is when an offensive player runs the ball either directly or handed off by the quarterback. The running back (can be quarterback, wide receiver, or another offensive player) tries to gain as many yards as possible by eluding defensive players. The play ends when the defense tackles the runner. The clock continues to run if the player is tackled within the field. \n\n* Pass Plays\n\nMost often the quarterback passes the football to another offensive player. A pass is complete if the ball is caught by another offensive player, usually the wide receiver, tight end or running back. f the ball hits the ground before someone catches it, it is called an incomplete pass. Time stops if the pass is dropped. The clock continues to run if the ball is caught and the player is tackled within the field. \n\n**SCORING**\n\nThe object of the game is to score the most points.\n\n* Touchdown = 6 Points\n\nTo score a touchdown, the ball must be carried across the goal line into the end zone, caught in the end zone, or a fumble recovered in the end zone, or an untouched kickoff recovered in the end zone by the kicking team. When a touchdown is scored the offense can then decide to add points to their score with either of these:\nExtra Point Kick = 1 Point\nTwo Point Conversion = 2 Points\n\n* Field Goal = 3 Points\n\nIf the offense cannot score a touchdown they may choose to kick a field goal through the goalposts at the back of the end zone. For a field goal to be scored the field goal kicker must kick the ball through the goal-post uprights and over the crossbar. The defense tries to block the kick and stop the ball from reaching the goal post.\n\nTeams most often go for a field goal when the kick is under 60 yards from the goal post (because it may be missed otherwise) and when it is forth down). \n\n* Safety = 2 POINTS\n\nA safety is worth two points is scored by the defense when the offensive ball carrier is tackled in their own goal line. \n\n**TURNOVERS**\n\nThe defense goal is to stop the offense or by stopping them within four downs or a turnover. A turnover happens when the offense loses the ball to the defense in one of two ways. \n\n* Fumble\nWhen an offensive player who is carrying the ball drops the ball before they are considered tackled it is a fumble. Any player on the field can recover the ball when it is fumbled, which includes the offense. The team that recovers a fumble either gets-or retains-possession of the ball.  \n\n* Interception\n\nThe defense can also catch the ball from the offense by intercepting their pass meant for an offensive player.\n\nSource: NFL.com",
