American Football

American football is a team sport played between two teams of eleven players on a rectangular field with goalposts at each end. The objective is to score points by advancing the ball into the opposing team’s end zone for a touchdown or kicking the ball through the opponent's goalposts for a field goal. The game is played in four quarters, and the team with the most points at the end wins.

The sport evolved from rugby and soccer in the United States, with its first game held in 1869 between Rutgers and Princeton. Walter Camp, known as the "Father of American Football," introduced key elements like the line of scrimmage, downs, and eleven-player teams.

Each team has an offensive, defensive, and special teams unit. The offence attempts to move the ball downfield, either by running or passing, while the defence tries to stop them and take control of the ball. The game is structured in plays, with teams having four downs to advance the ball 10 yards; failure results in the opposing team gaining possession.

American football is the most popular sport in the United States, with professional football, particularly the National Football League (NFL), being the most watched. College football is also highly popular, with its own leagues and tournaments. The Super Bowl, the NFL’s championship game, is one of the most-watched events globally.

Safety concerns have been a long-standing issue, particularly regarding concussions, leading to various efforts to improve player safety. Despite its international reach, American football has yet to gain the same level of popularity as other sports like soccer or basketball, though it is growing in countries like Canada, Mexico, and Japan.

There are several types of American football, each with its own variations in rules and gameplay, though the core elements remain the same. The most common forms include:

• Professional Football: This is the highest level of the sport, played in leagues like the National Football League (NFL). Teams consist of professional athletes, and the rules are standardised across the league. Professional football attracts the largest audience and generates significant revenue.
• College Football: Played by university teams in the United States, college football follows similar rules to the professional level but with slight differences in timing and player eligibility. It is a major part of the sports culture in the United States, with many teams competing in different conferences and national championships.
• High School Football: Played by students in secondary schools, high school football is often where players begin their journey in the sport. The rules are largely similar to college football, but with some modifications to make the game safer for younger players.
• Youth Football: This type is for children and young teens. It includes leagues like Pop Warner and others that focus on teaching the basics of the game. The rules may be further simplified, and safety measures are often stricter.
• Flag Football: A non-contact version of the game, flag football is played with similar rules, but instead of tackling, players remove a flag from the ball carrier’s waist. It is popular in schools and recreational leagues.
• Arena Football: This is a variation of the game played indoors with smaller teams and a shorter field. It is faster-paced and has different rules regarding the field size and scoring.

• National Football League (NFL): The NFL is the main professional football league in the United States. It consists of 32 teams divided into two conferences: the American Football Conference (AFC) and the National Football Conference (NFC). Each season ends with the Super Bowl, which is the championship game between the winners of the two conferences.
• College Football Playoff (CFP): College football teams in the top Football Bowl Subdivision (FBS) compete in a season-long schedule. The top four teams at the end of the season compete in a playoff, with the winner being crowned national champion.
• High School Football: In the United States, high school teams compete in state-level leagues. These competitions often lead to state championships, where the best teams in each state face off.
• Pop Warner and Youth Leagues: These are youth football leagues where children and young teenagers compete. Pop Warner is one of the largest youth leagues, with competitions at regional and national levels.
• Arena Football League (AFL): Although the Arena Football League ceased operations in 2019, arena football still takes place in other leagues. The competition is played indoors with a smaller field and teams.
• International Competitions: American football is also played internationally, with countries like Canada, Mexico, and Japan fielding national teams. The International Federation of American Football (IFAF) organises competitions like the IFAF World Championship, where teams from different nations compete.
• NFL International Series: The NFL also organises regular season games outside the United States, primarily in London, to promote the sport globally. These games feature teams from the NFL competing in international venues
