American football, known in the United States and Canada simply as football, is a competitive team sport. The object of the game is to score points by advancing the football towards the opposing team's end zone. The ball can be advanced by carrying the ball, or by throwing or handing it from one teammate to the other. Points can be scored in a variety of ways, including carrying the ball over the goal line, throwing the ball to another player past the goal line or kicking it through the goal posts on the opposing side. The winner is the team with the most points when the time expires and the last play ends.
Outside of the United States and Canada, the sport is usually referred to as American football (or sometimes as gridiron or gridiron football) to differentiate it from other football games, especially association football (soccer), rugby union and Australian Rules Football. In Japan, it is referred to as "amefuto" (an abbreviation). American football evolved as a separate sport from rugby union in the late 19th century. Arena football is an invented variant of American football. Canadian football, which also descended from rugby, is closely related to the American sport with a few key differences; the word "football" in Canada can mean American football or Canadian football depending on context.[1] Many in both Canada and the northern United States consider American and Canadian football to be two codes of the same game.
The object of American football is to score more points than the opposing team within a set time limit.
Field and players
The numbers on the field indicate the number of yards to the nearest end zone.American football is played on a rectangular field 120 yards (110 meters) long by 53 1/3 yards (49 meters) wide. The longer boundary lines are sidelines, while the shorter boundary lines are end lines. Near each end of the field is a goal line; they are 100 yards apart. A scoring area called an end zone extends 10 yards beyond each goal line to each end line.
Yard lines cross the field every 5 yards, and are numbered from each goal line to the 50-yard line, or midfield (similar to a typical rugby league field). Two rows of lines, known as hash marks, parallel the side lines near the middle of the field. All plays start with the ball on or between the hash marks.
At the back of each end zone are two goal posts (also called uprights) that are 18.5 feet apart (24 feet in high school). The posts are connected by a crossbar 10 feet from the ground. Successful kicks must go above the crossbar and between the uprights. (At professional, college, and some high school fields, the uprights and crossbar are attached by a curved bar to a padded post outside the field of play, to reduce the chance of players running into the supports. Many high schools, though, use an H-shaped structure located behind the endlines, allowing the structure to be used as a soccer goal as well.)
Each team has 11 players on the field at a time. However, teams may substitute for any or all of their players, if time allows, during the break between plays. As a result, players have very specialized roles, and almost all of the 53 players on an NFL team will play in any given game. Thus, teams are divided into three separate units: the offense, the defense and the special teams (see below). In the NFL, players' jersey numbers are distributed according to a strict system (e.g. quarterbacks always wear between 1-19).
Scoring
A team scores points by the following plays:
A touchdown (TD) is worth 6 points. A touchdown is scored when a player runs the ball into or catches a pass in his opponent's end zone.
After a touchdown, the scoring team attempts a conversion. The ball is placed at the other team's 3-yard line (the 2-yard line in the NFL). The team can attempt to kick it over the crossbar and through the goal posts in the manner of a field goal for 1 point (an extra point or point after touchdown (PAT)), or run or pass it into the end zone in the manner of a touchdown for 2 points (a two-point conversion). In collegiate and professional leagues, the extra point is usually preferred; its success rate is 94% in the NFL and 93.8% in the NCAA, compared to 43% in the NFL and 43.5% in the NCAA for two-point conversions. If the defense forces a turnover on an attempted conversion and runs the ball back to their opponent's endzone, they are awarded with 2 points (does not apply in the NFL).
A field goal (FG) is worth 3 points, and it is scored by kicking the ball over the crossbar and through the goal posts. Field goals may be placekicked (kicked when the ball is held vertically against the ground by a teammate) or drop-kicked. A field goal is usually attempted on fourth down instead of a punt when the ball is close to the goal line, or, when there is little or no time left to otherwise score.
A safety is worth 2 points. A safety is scored by the defense when the offensive player in possession of the ball is forced back into his own end zone and is tackled there, or fumbles the ball out of the end zone, or commits intentional grounding in the endzone. Certain penalties by the offense occurring in the end zone also result in a safety - these result in two points.

Well, if it wasn't a bunch of pony tail laden pretty boys sashaying their way across a pitch only to go down into a heap like they've been shot every time someone from the other team comes along and breathes on them wrong, we may have an interest. We do have a huge interest in the World Cup, but once every four years, both Mens and Women's World Cup. But other than that, we have a tough time having interest in a game that so many refer to as "the beautiful game" where the "beautiful game" may result in a 0-0 tie. I know the South American teams and their players do it quite a bit more often than any of the other countries' or players that come from those countries, but in all honesty, most Americans enjoy soccer. It's just the darn flopping. It's gotta stop. At times it rewards the flopper who's faking injury, and slows down the momentum for the player that did nothing wrong but play tough.

It does have a precarious name. However, just about every American will say that football is the best sport in the world and "soccer" sucks. Cause "soccer" indeed is the worse sport in the world. Football is similiar to rugyb but not quite. Go to nfl.com
