On television, a yellow line is electronically superimposed on the field to show the first down line to the viewing audience. There are two categories of kicks in football: scrimmage kicks, which can be executed by the offensive team on any down from behind or on the line of scrimmage, and free kicks. The free kicks are
1651-457: A group of Princeton players realized that, as the snap was uncontested, they could now hold the ball indefinitely to prevent their opponent from scoring. In 1881, in a game between Yale and Princeton, both teams 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 both teams' spectators and fans. A rule change
1778-533: 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 100 years and is considered 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. To try to prevent injuries, players are required to wear
1905-465: A lengthy investigation conducted by Brigadier General Gary M.

While the game between Rutgers and Princeton
2413-414: A more advantageous position to provide overwatch and fire support for Serial 2's movement out of the ambush. Upon exiting the gorge, and despite attempts by Serial 1 to signal a "friendly position", occupants of the lead vehicle of Serial 2 opened fire on Tillman's position, where he was fatally shot. The Army Special Operations Command initially claimed that there was an exchange with hostile forces. After

#17328589326512794-583: A player being paid to participate in a game of American football , although many athletic clubs in the 1880s 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 prohibited outright. Over time, professional play became increasingly common, and with it came rising salaries and unpredictable player movement, as well as
2921-427: A quarter ends, play continues until the down is completed. If certain fouls are committed during play while time has expired, the quarter may be extended through an untimed down .

At one point in his NFL career, Tillman turned down a five-year, $ 9 million contract offer from the St. Louis Rams out of loyalty to the Cardinals. Sports Illustrated football writer Paul Zimmerman named Tillman to his 2000 NFL All-Pro team after Tillman finished with 155 tackles (118 solo), 1.5 sacks, 2 forced fumbles, 2 fumble recoveries, 9 pass deflections, and 1 interception for 30 yards. Tillman finished his career with totals of 340 tackles, 2.5 sacks, 3 interceptions for 37 yards, 3 forced fumbles, 15 pass deflections, and 3 fumble recoveries in 60 career games.

Before the snap, the strategy had been to punt if a scrum resulted in bad field position. However,
4826-403: Is known as a two-point conversion . In general, the extra point is almost always successful, while the two-point conversion is a much riskier play with a higher probability of failure; accordingly, extra point attempts are far more common than two-point conversion attempts.

9144-430: 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. Players can line up temporarily in a position whose eligibility is different from what their number permits as long as they report the change immediately to the referee, who then informs the defensive team of the change. Neither team's players, except
9271-583: The basic facts of CPL Tillman's death – that it was caused by friendly fire, that the occupants of one vehicle in CPL Tillman's platoon were responsible, and that circumstances on the ground caused those occupants to misidentify friendly forces as hostile. None of the investigations suggested that CPL Tillman's death was anything other than accidental. Our review, as well as the investigation recently completed by Army CID, obtained no evidence contrary to those key findings. Tillman's brother Kevin testified before
9398-573: The college game during the late 1930s. Football, in general, became increasingly popular following the 1958 NFL Championship game between the Baltimore Colts and the New York Giants , still referred to as the "Greatest Game Ever Played". The game, a 23–17 overtime victory by the Colts, was seen by millions of television viewers and had a major influence on the popularity of the sport. This, along with
9525-594: The conference, as they favored a rugby-style game that allowed running with the ball. After playing McGill University using both American (known as "the Boston game ") for the first game and Canadian (rugby) rules for the second one, the Harvard players preferred the Canadian style of having only 11 men on the field, running the ball without having to be chased by an opponent, the forward pass, tackling, and using an oblong instead of
9652-541: The conservative NFL to expand to Dallas and Minnesota in an attempt to destroy the new league. Meanwhile, the AFL introduced many new features to professional football in the United States: official time was kept on a scoreboard clock rather than on a watch in the referee's pocket, as the NFL did; optional two-point conversions by pass or run after touchdowns; names on the jerseys of players; and several others, including expansion of

American football American football , referred to simply as football in the United States and Canada and also known as gridiron football , is a team sport played by two teams of eleven players on a rectangular field with goalposts at each end. The offense , the team with possession of
9906-413: The crossbars of the defense's goalposts. In practice, almost all field goal attempts are done via place kick. While drop kicks were common in the early days of the sport, the shape of modern footballs makes it difficult to reliably drop kick the ball. The last successful scoring play by drop kick in the NFL was accomplished in 2006; prior to that, the last successful drop kick had been made in 1941. After
10033-662: The death of Pat Tillman. On July 14, 2008, the House Committee on Oversight and Government Reform released a proposed report titled "Misleading Information from the Battlefield: The Tillman and Lynch Episodes". The committee stated that its "investigation was frustrated by a near universal lack of recall" among "senior officials at the White House" and the military. It concluded: The pervasive lack of recollection and absence of specific information makes it impossible for
10160-399: The defense is to prevent the offense from scoring by tackling the ball carrier or by forcing turnovers . Turnovers include interceptions (a defender catching a forward pass intended for the offense) and forced fumbles (taking possession of the ball from the ball-carrier). The defensive line (DL) consists of defensive ends (DE) and defensive tackles (DT). Defensive ends line up on
10287-430: The defensive backfield. They are divided into two types: middle linebackers (MLB) and outside linebackers (OLB). Linebackers tend to serve as the defensive leaders and call the defensive plays, given their vantage point of the offensive backfield. Their roles include defending the run, pressuring the quarterback, and tackling backs, wide receivers, and tight ends in the passing game. The defensive backfield , often called
10414-420: The defensive backs, there are two main types, cornerbacks , which play nearer the line of scrimmage and the sideline, whose main role is to cover the opposing team's wide receivers , and the safeties , who play further back near the center of the field, and who act as the last line of defense. American defensive formations usually includes two of each, a left and right cornerback, as well as a strong safety and
10541-472: The ends and sides of the field are known as the end lines and sidelines . Goal lines are marked 10 yards (9.1 m) inward from each end line. Weighted pylons are placed the sidelines on the inside corner of the intersections with 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 (0.91 m) increments. Yard lines , which can run
10668-404: The ends of the line, while defensive tackles line up inside, between the defensive ends. The primary responsibilities of defensive ends and defensive tackles are 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
10795-461: The enemy's withdrawal, his platoon's safe passage from the ambush kill zone, and his mortal wound. Corporal Tillman's personal courage, tactical expertise, and professional competence directly contributed to his platoon's overall success and survival. In making the ultimate sacrifice for his team and platoon, Corporal Patrick D. Tillman reflected great credit upon himself, the Joint Task Force, and
10922-499: The feet, hands, head, or sides, with the objective being to advance it into the opponent's goal. Rutgers won the game 6–4. Collegiate play continued for several years with games played using the rules of the host school. Representatives of Yale, Columbia , Princeton and Rutgers met on October 19, 1873, to create a standard set of rules for use by all schools. Teams were set at 20 players each, and fields of 400 by 250 feet (122 m × 76 m) were specified. Harvard abstained from
11049-419: The game clock based on the direction of the appropriate official . A separate play clock is used to show the amount of time within which the offense must initiate a play. The play clock is set to 25 seconds after certain administrative stoppages in play and to 40 seconds when play is proceeding without such stoppages. If the offense fails to start a play before the play clock reads "00", a delay of game foul
11176-618: The game unless major changes were made. In response, 62 colleges and universities met in New York City to discuss rule changes on December 28, 1905. These proceedings resulted in the formation of the Intercollegiate Athletic Association of the United States, later renamed the National Collegiate Athletic Association (NCAA). The legal forward pass was introduced in 1906, although its effect
11303-443: The ground or a tee; a holder may be used in either case. On a safety kick, the kicking team kicks the ball from their own 20-yard line. They can punt, drop kick or place kick the ball, but a tee may not be used in professional play. Any member of the receiving team may catch or advance the ball. 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
11430-434: The guards. The principal receivers are the wide receivers (WR) and the tight ends (TE). Wide receivers line up on or near the line of scrimmage, split outside the line. 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
11557-427: The head at less than 10 yards away, according to Army doctors. Jones reported that senior Army commanders, including General John Abizaid , knew of this fact within days of the shooting, but nevertheless approved the awarding of the Silver Star , Purple Heart , and a posthumous promotion to the rank of Corporal . Lieutenant General Stanley McChrystal approved the Silver Star citation on April 28, 2004, which gave
11684-539: 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 1920 as the American Professional Football Association, aimed to solve these problems. This new league's stated goals included an end to bidding wars over players, prevention of the use of college players, and abolition of the practice of paying players to leave another team. By 1922,
11811-448: The innovations introduced by the new American Football League (AFL) in the early 1960s, helped football to become the most popular sport in the United States by the mid-1960s. The rival AFL arose in 1960 and challenged the NFL's dominance. The AFL began in relative obscurity but eventually thrived, with an initial television contract with the ABC television network. The AFL's existence forced
11938-558: The investigation" because of the effect it could have on their recruiting efforts. After it happened, all the people in positions of authority went out of their way to script this. They purposely interfered with the investigation; they covered it up. I think they thought they could control it, and they realized that their recruiting efforts were going to go to hell in a handbasket if the truth about his death got out. They blew up their poster boy . He also blamed high-ranking Army officers for presenting "outright lies" to Tillman's family and to
12065-552: The locker room from the tunnel, and a television with a sound system displays Tillman's career highlights. The gate which opens to the field features an image of Pat Tillman facing the field, looking as if he is leading the team out. On Saturday, April 15, 2005, 5,000 participants turned out for the inaugural Pat's Run (which has become the annual fundraising event for the Pat Tillman Foundation) in Tempe . The racers traveled along
12192-487: The next value coin in the U.S. and Canada is called a dime ). Rarely, teams may employ seven or even eight defensive backs. Historic notable defensive backs include Hall-of-Famers Dick "Night Train" Lane , Mike Haynes , Ronnie Lott , and Troy Polamalu , Deion Sanders (aka "Primetime"), Darrelle Revis , and Ed Reed , among others. In 2019, the National Football League released its all-time team in honor of
12319-429: 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 farther down the field; if they are in field goal range , they might attempt to score
12446-429: The oval-shaped football , attempts to advance down the field by running with the ball or throwing it , while the defense , the team without possession of the ball, aims to stop the offense's advance and to take control of the ball for themselves. The offense must advance the ball at least ten yards in four downs or plays; if they fail, they turn over the football to the defense, but if they succeed, they are given
12573-445: The plane of the two end lines. The crossbar of these posts is 10 feet (3.0 m) above the ground, with vertical uprights at the end of the crossbar 18 feet 6 inches (5.64 m) apart for professional and collegiate play, and 23 feet 4 inches (7.11 m) apart for high school play. The uprights extend vertically 35 feet (11 m) on professional fields, a minimum of 10 yards (9.1 m) on college fields, and
12700-448: The point(s)-after-touchdown (PAT) or conversion, which is a single scoring opportunity. This is generally attempted from the two- or three-yard line, depending on the level of play. If the PAT is scored by a place kick or drop kick through the goal posts, it is worth one point, typically called the extra point. If the PAT is scored by what would normally be a touchdown, it is worth two points; this
12827-560: The position at 5 ft 11 in (1.80 m) tall. As a junior, he helped his team go undefeated that season as well as helping them make it to the Rose Bowl that year. In 1997, he was voted the Pac-10 Defensive Player of the Year. In the same year, Tillman was also named Arizona State's MVP. Tillman majored in marketing and graduated in three and a half years with a 3.85 GPA . He also earned many academic awards including:
12954-541: The primary proponents of the rugby-style game, compromised and did not request the name of the sport be changed to "rugby". The terms " gridiron " or "American football" are favored in English-speaking countries where other types of football are popular, such as the United Kingdom, Ireland, New Zealand, and Australia. American football evolved from the sports of rugby and soccer . Rugby, like American football,
13081-461: The public. On March 4, 2006, the U.S. Defense Department Inspector General directed the Army to open a criminal investigation of Tillman's death. The Army's Criminal Investigative Division was to determine whether Tillman's death was the result of negligent homicide. On March 26, 2007, the Pentagon released their report on the events surrounding Tillman's death and coverup. The report reads in part: ... we emphasize that all investigators established
13208-422: The punter. In football, the winner is the team that has scored more 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, or recovered in the opposing team's end zone. The scoring team then attempts a try, more commonly known as
13335-401: 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. The place kick is the standard method used to score points, because the pointy shape of the football makes it difficult to reliably drop kick. Once the ball has been kicked from a scrimmage kick, it can be advanced by the kicking team only if it
13462-631: 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 or goal-line situations. They are seldom used as receivers. The offensive line (OL) consists of several players whose primary function
13589-499: The role of minority players, actively recruited by the league in contrast to the NFL. The AFL also signed several star college players who had also been drafted by NFL teams. Competition for players heated up in 1965, when the AFL New York Jets signed rookie Joe Namath to a then-record $ 437,000 contract (equivalent to $ 4.23 million in 2023). A five-year, $ 40 million NBC television contract followed, which helped to sustain
13716-469: The scenario as described", also noting that the wound entrances appeared as though he had been shot with an M16 rifle from fewer than 10 yards (9.1 m) away. A possible motive was not identified. When officers and soldiers were asked during a criminal investigation, they said they were certain the shooting was accidental. According to one of his fellow soldiers, Tillman "was popular among his fellow soldiers and had no enemies." In addition, in response to
13843-503: The secondary, consists of cornerbacks (CB) and safeties (S). Safeties are themselves divided into free safeties (FS) and strong safeties (SS). Cornerbacks line up outside the defensive formation, typically opposite a receiver to be able to cover them. Safeties line up between the cornerbacks but farther back in the secondary. Safeties tend to be viewed as "the last line of defense" and are responsible for stopping deep passing plays as well as breakout running plays. The special teams unit
13970-480: The service. According to Krakauer in his book Where Men Win Glory , the extensive coverup that followed Tillman's death included the military's order to Tillman's comrades to lie to his family at the funeral. Tillman's parents have sharply criticized the Army's handling of the incident; Tillman's mother believed that "this lie was to cover their image," while Tillman's father believed that the Army "purposely interfered in
14097-446: The size and shape of the football. The sport is closely related to Canadian football , which evolved in parallel with and at the same time as the American game, although its rules were developed independently from those of Camp. Most of the features that distinguish American football from rugby and soccer are also present in Canadian football. The two sports are considered the primary variants of gridiron football . American football
14224-428: The sport maintains a growing following in the rest of North America, Europe, Brazil, and Japan. In the United States, American football is referred to as "football". The term "football" was officially established in the rulebook for the 1876 college football season , when the sport first shifted from soccer-style rules to rugby-style rules. Although it could easily have been called "rugby" at this point, Harvard, one of

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
14478-408: The winning team decides to defer, the losing team chooses the option the winning team did not select—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 allows the other team to choose which goal to defend. Teams switch goals following the first and third quarters. If a down is in progress when

Completed in October 2010, the Mike O'Callaghan–Pat Tillman Memorial Bridge spans the Colorado River between Nevada and Arizona. Lincoln Law School of San Jose has established the Pat Tillman Scholarship in honor of Tillman. Tillman's father earned his Juris Doctor from Lincoln in 1983. On Sunday, September 19, 2004, all teams of
14732-408: The young league. The bidding war for players ended in 1966 when NFL owners approached the AFL regarding a merger, and the two leagues agreed on one that took full effect in 1970. 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. This championship game began play at the end of
14859-573: Was also burned; "a blatant violation of protocol." Several soldiers were punished for their actions by being removed from the United States Army Rangers . Jones believed that Tillman should retain his medals and promotion, since, according to Jones, he intended to engage the enemy and behaved heroically. Tillman's family was not informed of the finding that he was killed by friendly fire until weeks after his memorial service, although at least some senior Army officers knew of that fact prior to
14986-445: Was catcher for his baseball team, but did not make the varsity team. In his sophomore year he decided to concentrate on football. Tillman then went to Arizona State University on a football scholarship. Tillman was very close to his family and high school friends. He repeatedly mentioned in his personal journals during wartime service that he drew strength from and deeply valued his closest friendships, parents, wife and family. Tillman
15113-557: Was discovered he had been killed by friendly fire . Tillman played college football for the Arizona State Sun Devils , earning first-team All-American honors in 1997. After four seasons in the NFL, Tillman joined the Army Rangers and served several combat tours before he was killed in the mountains of Afghanistan. At first, the army reported that Tillman had been killed by enemy fire. A month later, on May 28, 2004,
15240-418: Was initially minimal due to the restrictions placed on its use. The idea of a 40-yard-wider field was opposed by Harvard due to the size of the new Harvard Stadium . Other rule changes introduced that year included the reduction of playing time from 70 to 60 minutes and an increase of the distance required for a first down from 5 to 10 yards (4.6 to 9.1 m). To reduce infighting and dirty play between teams,
15367-467: Was most likely killed as a result of fire from a M249 light machine gun . The M249 uses the same ammunition as the M16 rifle and M4 carbine, but is capable of higher rates of fire. This would allow a competent user to place three bullets within a several-inch target from 40 or 50 yards away, even from a moving vehicle. On July 26, 2007, Chris Matthews reported on Hardball that Tillman's death may have been
15494-440: Was necessary to prevent this strategy from taking hold, and a reversion to the scrum was considered. However, Camp successfully proposed a rule in 1882 that limited each team to three downs , or tackles, to advance the ball 5 yards (4.6 m). 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
15621-431: Was played on November 6, 1869 , between two college teams, Rutgers and Princeton , using rules based on the rules of soccer at the time. A set of rule changes drawn up from 1880 onward by Walter Camp , the "Father of American Football", established the snap , the line of scrimmage , eleven-player teams, and the concept of downs. Later rule changes legalized the forward pass , created the neutral zone , and specified
15748-542: 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 1992 to determine a national champion of college football. The first was the Bowl Coalition , in place from 1992 to 1994. This was replaced in 1995 by the Bowl Alliance , which gave way to
15875-485: Was subsequently deployed to Afghanistan, and posted at FOB Salerno . On April 22, 2004, he was initially reported to have been killed by enemy combatants. An Afghan Militia Force allied soldier, Sayed Farhad, was also killed in the action. Tillman's platoon leader, First Lieutenant David Uthlaut, and his radiotelephone operator (RTO), 19-year-old Jade Lane, were wounded in the incident. The Army initially claimed that Tillman and his unit were attacked in an apparent ambush on
16002-509: Was to deceive a whole nation." Citation: The President of the United States of America, authorized by Act of Congress July 9, 1918 (amended by an act of July 25, 1963), takes pride in presenting the Silver Star (Posthumously) to Corporal Patrick D. Tillman, United States Army, for gallantry in action while serving with the 2nd Battalion, 75th Ranger Regiment, during action in Afghanistan on 22 April 2004, against an armed enemy while serving as
16129-451: Was very committed to his high school sweetheart, Marie Ugenti, whom he married shortly before his enlistment in the Army. He also was very close with his brother, Kevin, who enlisted with and served alongside him. He started his college career as a linebacker for Arizona State University in 1994, when he secured the last remaining scholarship for the team. Tillman excelled as a linebacker at Arizona State, despite being relatively small for
