A football team is the collective name given to a group of players selected together in the various team sports known as football.
Such teams could be selected to play in an against an opposing team, to represent a football club, group, state or nation, an All-star team or even selected as a hypothetical team (such as a Dream Team or Team of the Century) and never play an actual match.
There are several varieties of football, with the most notable being Association football, Gridiron football, Australian rules football, Gaelic football, rugby league and rugby union. The number of players selected for each team within these varieties and their associated codes can vary substantially. In some, use of the word "team" is sometimes limited to those who play on the field in a match and does not always include other players who may take part as replacements or emergency players. "Football squad" may be used to be inclusive of these support and reserve players.
The term football club is the most commonly used for a sports club which is an organised or incorporated body with a president, committee and a set of rules responsible for ensuring the continued playing existence of one or more teams which are selected for regular competition play ( and which may participate in several different divisions or leagues). The oldest football clubs date back to the early 19th century. The word team and club are sometimes used interchangeably by supporters, although typically refers to the team within the club playing in the highest division or competition.
American football is played on a 100-yard field which is marked by ten-yard intervals. Each team has 11 players on the field at any time. All players wear uniforms with numbers which are reserved for certain positions. Each player has a special role and teams are divided into offense, defense and special teams.
In formation, when one team plays offense, the other reciprocates by sending in a defensive team. The offense consists of five offensive players whose job is to protect the passes and clear the way for the runners by blocking members of the defense. The lineman play in the middle or center of the field. Outside the center are the guards and at the periphery are the tackles.
The quarterback (QB) receives the snap in most plays. He may either toss the ball to a running back, throw it to a receiver or run with the ball himself. The Quarterback is the leader of the offensive team and calls out the plays that are signaled to him from the sidelines. The running backs line up behind the QB and have great skill running with the ball. They can even block, catch or pass the ball to others. Wide receivers usually play near the sidelines and are usually very tall, agile and fast. They have the necessary skill for catching passes at full speed and sometimes may block the opponents.
