Harvard abstained from the conference, as they favored a rugby-style game that allowed running with the ball. An Harvard-Yale game played under rugby-style rules was observed by two impressed Princeton athletes.
These players introduced the sport to Princeton, a feat the Professional Football Researchers Association compared to "selling refrigerators to Eskimos.
Yale player Walter Camp , now regarded as the "Father of American Football",   secured rule changes in that reduced the size of each team from 15 to 11 players and instituted the snap to replace the chaotic and inconsistent scrum.
The introduction of the snap resulted in unexpected consequences. Prior to the snap, the strategy had been to punt if a scrum resulted in bad field position.
However, a group of Princeton players realized that, as the snap was uncontested, they now could hold the ball indefinitely to prevent their opponent from scoring.
In , both teams in a game between Yale-Princeton used this strategy to maintain their undefeated records. Each team held the ball, gaining no ground, for an entire half, resulting in a 0—0 tie.
This "block game" proved extremely unpopular with the spectators and fans of both teams. A rule change was necessary to prevent this strategy from taking hold, and a reversion to the scrum was considered.
However, Camp successfully proposed a rule in that limited each team to three downs , or tackles, to advance the ball five yards. Failure to advance the ball the required distance within those three downs would result in control of the ball being forfeited to the other team.
This change effectively made American football a separate sport from rugby, and the resulting five-yard lines added to the field to measure distances made it resemble a gridiron in appearance.
Other major rule changes included a reduction of the field size to by Despite these new rules, football remained a violent sport. Dangerous mass-formations, which involved interlocking interference, like the flying wedge resulted in serious injuries and deaths.
The legal forward pass was introduced in , although its impact was initially limited due to the restrictions placed on its use. Other rule changes introduced that year included the reduction of the time of play from 70 to 60 minutes and the increase of the distance required for a first down from 5 to 10 yards 9.
To reduce infighting and dirty play between teams, the neutral zone was created along the width of the football. This is the first recorded instance of a player being paid to participate in a game of American football , although many athletic clubs in the s offered indirect benefits, such as helping players attain employment, giving out trophies or watches that players could pawn for money, or paying double in expense money.
Despite these extra benefits, the game had a strict sense of amateurism at the time, and direct payment to players was frowned upon, if not outright prohibited.
Over time, professional play became increasingly common, and with it came rising salaries and unpredictable player movement, as well as the illegal payment of college players who were still in school.
The National Football League NFL , a group of professional teams that was originally established in as the American Professional Football Association, aimed to solve these problems.
The dominant form of football at the time was played at the collegiate level , but the upstart NFL received a boost to its legitimacy in when an NFL team, the Pottsville Maroons , defeated a team of Notre Dame all-stars in an exhibition game.
The game, a 23—17 overtime victory by the Colts, was seen by millions of television viewers and had a major impact on the popularity of the sport.
This, along with the innovations introduced by the new American Football League AFL in the early s, helped football to become the most popular sport in the United States by the mids.
The bidding war for players ended in , when NFL owners approached the AFL regarding a merger, and the two leagues agreed on one that would take full effect in This agreement provided for a common draft that would take place each year, and it instituted an annual World Championship game to be played between the champions of each league.
That game began play at the end of the season. Once the merger was completed, it was no longer a championship game between two leagues, and reverted to the NFL championship game, which came to be known as the Super Bowl.
College football maintained a tradition of postseason bowl games. Each bowl game would be associated with a particular conference, and earning a spot in a bowl game was the reward for winning a conference.
This arrangement was profitable, but it tended to prevent the two top-ranked teams from meeting in a true national championship game, as they would normally be committed to the bowl games of their respective conferences.
Several systems have been used since to determine a national champion of college football. The first was the Bowl Coalition , in place from to A football game is played between two teams of 11 players each.
Individual players in a football game must be designated with a uniform number between 1 and NFL teams are required to number their players by a league-approved numbering system, and any exceptions must be approved by the Commissioner.
The role of the offensive unit is to advance the football down the field with the ultimate goal of scoring a touchdown. The offensive team must line up in a legal formation before they can snap the ball.
An offensive formation is considered illegal if there are more than four players in the backfield or fewer than five players numbered 50—79 on the offensive line.
Interior offensive linemen are not allowed to move until the snap of the ball. The quarterback is the leader of the offense. Either the quarterback or a coach calls the plays.
Quarterbacks typically inform the rest of the offense of the play in the huddle before the team lines up.
The quarterback lines up behind the center to take the snap and then hands the ball off, throws it or runs with it.
The primary role of the halfback, also known as the running back or tailback, is to carry the ball on running plays. Halfbacks may also serve as receivers.
Fullbacks tend to be larger than halfbacks and function primarily as blockers, but they are sometimes used as runners in short-yardage situations  and are seldom used in passing situations.
The offensive line OL consists of several players whose primary function is to block members of the defensive line from tackling the ball carrier on running plays or sacking the quarterback on passing plays.
The principal receivers are the wide receivers WR and the tight ends TE. The main goal of the wide receiver is to catch passes thrown by the quarterback,  but they may also function as decoys or as blockers during running plays.
Tight ends line up outside the tackles and function both as receivers and as blockers. The role of the defense is to prevent the offense from scoring by tackling the ball carrier or by forcing turnovers interceptions or fumbles.
Defensive ends line up on the ends of the line, while defensive tackles line up inside, between the defensive ends. The primary responsibilities of defensive ends and defensive tackles is to stop running plays on the outside and inside, respectively, to pressure the quarterback on passing plays, and to occupy the line so that the linebackers can break through.
Linebackers line up behind the defensive line but in front of the defensive backfield. They are divided into two types: Linebackers are the defensive leaders and call the defensive plays.
Their diverse roles include defending the run, pressuring the quarterback, and guarding backs, wide receivers and tight ends in the passing game.
The defensive backfield , often called the secondary, consists of cornerbacks CB and safeties S. Safeties are themselves divided into free safeties FS and strong safeties SS.
Safeties are the last line of defense, and are responsible for stopping deep passing plays as well as running plays. The special teams unit is responsible for all kicking plays.
Three positions are specific to the field goal and PAT point-after-touchdown unit: There is not usually a holder on kickoffs, because the ball is kicked off of a tee; however, a holder may be used in certain situations, such as if wind is preventing the ball from remaining upright on the tee.
The player on the receiving team who catches the ball is known as the kickoff returner KR. The positions specific to punt plays are the punter P , long snapper, upback and gunner.
The long snapper snaps the football directly to the punter, who then drops and kicks it before it hits the ground. Gunners line up split outside the line and race down the field, aiming to tackle the punt returner PR — the player that catches the punt.
Upbacks line up a short distance behind the line of scrimmage, providing additional protection to the punter. In American football, the winner is the team that has scored the most points at the end of the game.
There are multiple ways to score in a football game. The touchdown TD , worth six points, is the most valuable scoring play in American football.
A touchdown is scored when a live ball is advanced into, caught in, or recovered in the end zone of the opposing team. A PAT is most commonly attempted from the two- or three-yard line, depending on the level of play.
If scored by a placekick or dropkick through the goal posts, it is worth one point, and is typically called the extra point.
In such a case, a successful attempt is called the two-point conversion  and is worth two points. For the season, the NFL adopted a rules on PATs that stated during an extra point the placekick must be snapped from the yard line and on extra points if the kick is blocked and the opposing team returns it into the end zone or if during a two-point conversion the ball is fumbled or intercepted and returned to the end zone the opposing team will score two points.
No points are awarded on a failed extra point or two-point conversion attempt, although under a rare set of circumstances it is possible to score a safety, worth one point, if the defense takes the ball back into its own end zone and is downed there.
A safety is scored when the ball carrier is tackled in their own end zone. Safeties are worth two points, which are awarded to the defense.
Lines marked along the ends and sides of the field are known respectively as the end lines and sidelines , and goal lines are marked 10 yards 9.
Weighted pylons are placed on the inside corner of the intersections of the goal lines and end lines. White markings on the field identify the distance from the end zone.
Inbound lines, or hash marks , are short parallel lines that mark off 1 yard 0. Yard lines , which can run the width of the field, are marked every 5 yards 4.
A one-yard-wide line is placed at each end of the field; this line is marked at the center of the two-yard line in professional play and at the three-yard line in college play.
Numerals that display the distance from the closest goal line in yards are placed on both sides of the field every ten yards.
Goalposts are located at the center of the plane of each of the two end lines. The crossbar of these posts is ten feet 3.
Goal posts are padded at the base, and orange ribbons are normally placed at the tip of each upright. The football itself is an oval ball, similar to the balls used in rugby or Australian rules football.
Football games last for a total of 60 minutes in professional and college play and are divided into two-halves of 30 minutes and four-quarters of 15 minutes.
The losing team, unless the winning team decides to defer, is allowed to choose the option the winning team did not select, and receives the option to receive, kick, or select a goal to defend to begin the second half.
Most teams choose to receive or defer, because choosing to kick the ball to start the game would allow the other team to choose which goal to defend.
Games last longer than their defined length due to play stoppages — the average NFL game lasts slightly over three hours. An operator is responsible for starting, stopping and operating the game clock based on the direction of the appropriate official.
If the play clock expires before the ball has been snapped or free-kicked, a delay of game foul is called on the offense. The play clock is set to 40 seconds in professional and college football and to 25 seconds in high school play or following certain administrative stoppages in the former levels of play.
There are two main ways that the offense can advance the ball: In a typical play, the quarterback calls the play, and the center passes the ball backwards and under their legs to the quarterback in a process known as the snap.
The quarterback then either hands the ball off to a back, throws the ball or runs with it. The play ends when the player with the ball is tackled or goes out of bounds, or a pass hits the ground without a player having caught it.
A forward pass can only be legally attempted if the passer is behind the line of scrimmage, and only one forward pass can be attempted per down. The offense is given a series of four plays, known as downs.
If the offense advances ten or more yards in the four downs, they are awarded a new set of four downs. If they fail to advance ten yards, possession of the football is turned over to the defense.
In most situations, if the offense reaches their fourth down they will punt the ball to the other team, which forces them to begin their drive from further down the field; if they are in field goal range , they might also attempt to score a field goal.

Nfl American Football VideoThe Rules of American Football - EXPLAINED! (NFL) Wenn dreams casino mobile login Spielergruppe längere Zeit erfolgreich zusammenspielt, etablieren sich bei Fans und Presse Spitznamen. Tierschützer kritisieren die NFL für ihre Regularien, welche verlangen, dass glücksrad online drehen Spielbälle aus echtem Rindsleder gefertigt werden. Der Titel dieses Artikels ist mehrdeutig. Dies dient dem Schutz des universitären Spielbetriebs und auch derjenigen Spieler, die ihre Ausbildung für eine mögliche Profi-Karriere opfern würden. All Pro Team Die Saison beginnt nach einer mehrwöchigen Preseason , in der nur Testspiele bestritten werden. Rams ziehen in den Super Bowl ein. In diesem Draft bekam jedes Jahr die letztplatzierte Mannschaft das Recht, als erste mit einem Nachwuchsspieler ihrer Wahl zu verhandeln, danach konnte das zweitletzte Team einen Neuling benennen, und so weiter in der Rangfolge. Vielen Spielern wurde genau dies von der Pike auf beigebracht, sodass sie ihre Technik jetzt umstellen müssen. Nach dem Krieg wurde erst langsam von diesem Prinzip abgewichen; als letztes Team verpflichteten die Washington Redskins ihren ersten farbigen Spieler. Bier exen kann er übrigens auch ganz gut.

Tennessee Titans 26 Philadelphia Eagles Any member of the receiving team may catch or advance the ball, and the ball may be recovered by the kicking team once it has gone at least ten yards and has touched the ground or has been touched by any member of the receiving team.
The three types of scrimmage kicks are place kicks, drop kicks, and punts. Only place kicks and drop kicks can score points. If it is touched or recovered by the kicking team beyond this line, it becomes dead at the spot where it was touched.
This prohibits the defense from blocking into or tackling the receiver, but the play ends as soon as the ball is caught and the ball may not be advanced.
Officials are responsible for enforcing game rules and monitoring the clock. All officials carry a whistle and wear black-and-white striped shirts and black hats except for the referee, whose hat is white.
Each carries a weighted yellow flag that is thrown to the ground to signal that a foul has been called. An official who spots multiple fouls will throw their hat as a secondary signal.
Another set of officials, the chain crew , are responsible for moving the chains. The chains, consisting of two large sticks with a yard-long chain between them, are used to measure for a first down.
The chain crew stays on the sidelines during the game, but if requested by the officials they will briefly bring the chains on to the field to measure.
A typical chain crew will have at least three people — two members of the chain crew will hold either of the two sticks, while a third will hold the down marker.
The down marker, a large stick with a dial on it, is flipped after each play to indicate the current down, and is typically moved to the approximate spot of the ball.
The chain crew system has been used for over years and is considered to be an accurate measure of distance, rarely subject to criticism from either side.
Football is a full-contact sport, and injuries are relatively common. Most injuries occur during training sessions, particularly ones that involve contact between players.
At a minimum players must wear a football helmet and a set of shoulder pads , but individual leagues may require additional padding such as thigh pads and guards, knee pads, chest protectors, and mouthguards.
The most common types of injuries are strains , sprains , bruises , fractures, dislocations , and concussions.
More specifically, each year a player played tackle football under age 12 predicted earlier onset of cognitive, behavioral, and mood problems by an average of two and a half years.
College football is the third-most popular sport in the United States, behind professional baseball and professional football. High school football is the most popular sport in the United States played by boys; over 1.
The NFHS is the largest organization for high school football, with member associations in all 50 states as well as the District of Columbia.
USA Football is the governing body for youth and amateur football,  and Pop Warner Little Scholars is the largest organization for youth football.
Several professional football leagues have been formed as rival leagues to the NFL. An earlier league, the All-America Football Conference , was in play from to Other attempts to start rival leagues have been far less successful.
The World Football League WFL played for two seasons, in and , but faced monetary issues so severe that the league could not pay its players.
In its second and final season the WFL attempted to establish a stable credit rating, but the league disbanded before its second season could be completed.
American football leagues exist throughout the world, but the game has yet to achieve the international success and popularity of baseball and basketball.
All of these countries rank far below the United States, which is dominant at the international level.
Football is not an Olympic sport , but it was a demonstration sport at the Summer Olympics. American football also has the issue of global visibility.
Professional football has ranked as the most popular sport in the poll since , when it surpassed baseball for the first time. In a study, the NCAA estimated there were around 1.
American football also plays a significant role in American culture. The day on which the Super Bowl is held is considered a de facto national holiday ,  and in parts of the country like Texas , the sport has been compared to a religion.
Merit is rewarded, not punished. Masculinity is celebrated, not feminized. People of various beliefs and backgrounds — a melting pot, if you will — must unify for a common goal for the team to be successful".
The safety of the sport has also sparked national controversy in American popular culture. It is often received as "overly aggressive", and defamiliarized in popular culture.

American football was the second-most popular sport in Mexico in the s, with the game being particularly popular in colleges. American football is the fifth most popular sport in Mexico and the country has the highest rating of the NFL outside the United States.
Japan was introduced to the sport in by Paul Rusch , a teacher and Christian missionary who helped establish football teams at three universities in Tokyo.
Play was halted during World War II, but began to grow in popularity again after the war. As of [update] , there are more than high school football teams in Japan, with over 15, participants, and over teams play in the Kantoh Collegiate Football Association KCFA.
Europe is a major target for expansion of the game by football organizers. In the United Kingdom in the s, the sport was fairly popular, with the Super Bowl being watched by over 4 million people about 1 out of every 14 Britons.
Super Bowl viewership has also rebounded, with over 4. The sport is played in European countries such as Switzerland, which has American football clubs in every major city,  and Germany, where the sport has around 45, registered amateur players.
But in these countries American football has not yet reached the same level of popularity it has, for example, in North America.
Rumors were that a Pro Bowl edition could be held there. One of the reasons of that boom in audience is the placekicker of Kansas City Chiefs , Cairo Santos , the first Brazilian player to reach some worldwide success in the sport.
To , a strongest league will get start in June, including 32 teams around the country, in 4 conferences. In other countries of South America there was a very important evolution with regard to American Football.
In was begun the practice of this sport in Argentina. Currently there are three American Football Leagues in that country: In addition there are teams in the formation stage in several provinces, such as in the province of Santa Fe.
Canadian football , the predominant form of football in Canada, is closely related to American football — both sports developed from rugby, and the two sports are considered to be the chief variants of gridiron football.
Punting is illegal, and kickoffs are attempted from the goal line. Large overhead nets deflect forward passes and kicks that hit them, and deflected kicks are live balls that may be recovered by either team.
Like in arena football, teams in indoor football leagues play in arenas, but games are only attended by a small number of fans, and most players are semi-professional athletes.
Indoor football leagues are unstable, with franchises regularly moving from one league to another or merging with other teams, and teams or entire leagues dissolving entirely.
There are several non-contact variants of American football, such as flag football. A game of touch football may require that the player be touched with either one or two hands to be considered down, depending on the rules used.
