The Basics of Football

Football is a game that combines running, passing, and kicking. It is a popular sport in many countries.

It is played by two teams, each with 11 players. The team that has possession of the ball is called the offense, and its goal is to advance the ball down the field and score points by crossing the goal line or getting into an area called the end zone.

The offensive team can change up its plays by using players in different positions, called ‘positions’. Each team may have up to ten players in these positions, and they can move between them at any time during a play.

Each player has the responsibility of moving forward to receive a pass from their ‘quarterback’. There are a number of rules that govern how this can happen, including that the quarterback must be on his side of the line of scrimmage at the start of the play.

Incomplete passes occur when a pass flies out of bounds or touches the ground before it is caught. If this occurs, the ball is returned to the original line of scrimmage for the next down.

Turnovers on downs occur when a team fails to gain a first down in four downs, or a player runs out of bounds or is hit by a defensive player. If a player is tackled behind the line of scrimmage before they are able to run, it is called a sack.
