Overview

In modern American football, the starting quarterback is usually the leader of the offense, and their successes and failures can have a significant impact on the fortunes of their team. Accordingly, the quarterback is among the most glorified, scrutinized, and highest-paid positions in team sports. ''

were not stars, linebacker Junior Seau said, "You can't imagine the security we feel as teammates knowing we have two quarterbacks who have performed in this league and know how to handle themselves as players and as leaders". Commentators have noted the "disproportionate importance" of the quarterback, describing it as the "most glorified—and scrutinized—position" in team sports. It is believed that "there is no other position in sports that 'dictates the terms' of a game the way quarterback does", whether that impact is positive or negative, as "Everybody feeds off of what the quarterback can and cannot do...Defensively, offensively, everybody reacts to what threats or non-threats the quarterback has. Everything else is secondary". "An argument can be made that quarterback is the most influential position in team sports, considering he touches the ball on virtually every offensive play of a far shorter season than baseball, basketball or hockey—a season in which every game is vitally important". Most consistently successful NFL teams (for instance, multiple Super Bowl appearances within a short period of time) have been centered around a single starting quarterback; the one exception was the Washington Redskins under head coach Joe Gibbs who won three Super Bowls with three different starting quarterbacks from 1982 to 1991. Many of these NFL dynasties ended with the departure of their starting quarterback. On a team's defense, the middle linebacker is regarded as "quarterback of the defense" and is often the defensive leader, since he must be as smart as he is athletic. The middle linebacker (MLB), sometimes known as the "Mike", is the only inside linebacker in the 4–3 scheme.


Backup

Compared to other positions in gridiron football, the backup quarterback gets considerably less playing time than the starting quarterback. While players at many other positions may rotate in and out during a game, and even a starter at most other positions rarely plays every snap, a team's starting quarterback often remains in the game for every play, often to give the team consistent leadership. That means that even a team's primary backup may go an entire season without a meaningful offensive snap. While their primary role may be to be available in case of injury to the starter, the backup quarterback may also have additional roles such as a holder on placekicks or as a punter, and will often play a key role in practice, serving as the upcoming opponent's quarterback during the preceding week's practices. A backup quarterback may also be put in during "

Trends and other roles

In addition to their main role, quarterbacks are occasionally used in other roles. Most teams utilize a backup quarterback as their holder on placekicks. A benefit of using quarterbacks as holders is that it would be easier to pull off a fake field goal attempt, but many coaches prefer to use punters as holders because a punter will have far more time in practice sessions to work with the kicker than any quarterback would.

Dual-threat quarterbacks

A dual-threat quarterback possesses the skills and physique to run with the ball if necessary. With the rise of several blitz-heavy defensive schemes and increasingly faster defensive players, the importance of a mobile quarterback has been redefined. While arm power, accuracy, and

presence—the ability to successfully operate from within the "pocket" formed by his blockers—are still the most important quarterback virtues, the ability to elude or run past defenders creates an additional threat that allows greater flexibility in a team's passing and running game. Dual-threat quarterbacks have historically been more prolific at the college level. Typically, a quarterback with exceptional quickness is used in an option offense, which allows the quarterback to hand the ball off, run it himself or pitch it to a running back shadowing him to the outside. This type of offense forces defenders to commit to the running back up the middle, the quarterback around the end or the running back trailing the quarterback. It is then that the quarterback has the "option" to identify which matchup is most favorable to the offense as the play unfolds and exploit that defensive weakness. In the college game, many schools employ several plays that are designed for the quarterback to run with the ball. This is much less common in professional football, except for a

Two-quarterback system

Some teams employ a strategy that involves the use of more than one quarterback during the course of a game. This is more common at lower levels of football, such as high school or small college, but rare in major college or professional football. There are four circumstances in which a two-quarterback system may be used. The first is when a team is in the process of determining which quarterback will eventually be the starter, and may choose to use each quarterback for part of the game in order to compare the performances.

. The second is a starter–reliever system, in which the starting quarterback splits the regular season playing time with the backup quarterback, although the former will start playoff games. This strategy is rare, and was last seen in the NFL in the "WoodStrock" combination of Don Strock and David Woodley, which took the Miami Dolphins to the Epic in Miami in 1982 and Super Bowl XVII the following year. The starter–reliever system is distinct from a one-off situation in which a starter is benched in favor of the backup because the switch is part of the game plan (usually if the starter is playing poorly for that game), and the expectation is that the two players will assume the same roles game after game. The third is if a coach decides that the team has two quarterbacks who are equally effective and proceeds to rotate the quarterbacks at predetermined intervals, such as after each quarter or after each series. Southern California high school football team Corona Centennial operated this model during the 2014 football season, rotating quarterbacks after every series. In a game against the

. This strategy had all but disappeared from professional American football, but returned to some extent with the advent of the "wildcat" offense. There is debate within football circles as to the effectiveness of the so-called "two-quarterback system". Many coaches and media personnel remain skeptical of the model. Teams such as USC (Southern California), OSU (Oklahoma State), Northwestern and smaller West Georgia have utilized the two-quarterback system; West Georgia, for example, uses the system due to the skillsets of its quarterbacks. As recently as 2020, Oregon, who had two quarterbacks capable of starting (Boston College transfer Anthony Brown and sophomore Tyler Shough), utilized a similar tactic in the 2020 Pac-12 Football Championship Game, giving Shough the start but inserting the dual-threat Brown on short-yardage plays, red zone situations and the final drive of the game. Teams like these use this situation because of the advantages it gives them against defenses of the other team, so that the defense is unable to adjust to their gameplan.


History

The quarterback position dates to the late 1800s, when American Ivy League schools playing a form of rugby union imported from the United Kingdom began to put their own spin on the game. Walter Camp, a prominent athlete and rugby player at Yale University, pushed through a change in rules at a meeting in 1880 that established a line of scrimmage and allowed for the football to be snap (American and Canadian football), snapped to a quarterback. The change was meant to allow for teams to strategize their play more thoroughly and retain possession more easily than was possible in the chaos of a scrum (rugby), scrummage in rugby. In Camp's formulation, the "quarter-back" was the person who received a ball snapped back with another player's foot. Originally he was not allowed to run forward of the line of scrimmage: In the primary formation of Camp's time, there were four "back" positions, with the tailback playing furthest back, followed by the fullback, the halfback, and the quarterback closest to the line. As the quarterback was not allowed to run past the line of scrimmage, and the

had not yet been invented, their primary role was to receive the snap from the center, and immediately hand or toss the ball backwards to the fullback or halfback to run. By the early 1900s, their role had been further reduced, as teams began to employ longer, direct snaps to one of the other backs (who by rule ''were'' allowed to run) and the quarterback became the primary "blocking back", leading the way through the defense but rarely carrying the ball themselves. This was the primary strategy of the single wing offense which was popular during the early decades of the 20th century. After the growth of the forward pass, the role of the quarterback changed again. The quarterback would later be returned to his role as the primary receiver of the snap after the advent of the T-formation offense, especially under the success of former single wing tailback, and later T-formation quarterback, Sammy Baugh. The requirement to stay behind the line of scrimmage was soon rescinded, but it was later reimposed in six-man football. The exchange between the person snapping the ball (typically the Center (gridiron football), center) and the quarterback was initially an awkward one because it involved a kick. At first, centers gave the ball a small boot, and then picked it up and handed it to the quarterback. By 1889, Yale center Bert Hanson was bouncing the ball on the ground to the quarterback between his legs. The following year, a rule change officially made snapping the ball using the hands between the legs legal. Several years later, Amos Alonzo Stagg at the Chicago Maroons football, University of Chicago invented the lift-up snap: the center passed the ball off the ground and between his legs to a standing quarterback. A similar set of changes were later adopted in Canadian football as part of the Burnside rules, a set of rules proposed by John Meldrum "Thrift" Burnside, the captain of the Toronto Varsity Blues#Football, University of Toronto's football team. The change from a scrummage to a "scrimmage" made it easier for teams to decide what plays they would run before the snap. At first, the captains of college teams were put in charge of play calling, indicating with shouted codes which players would run with the ball and how the men on the line were supposed to Blocking (American football), block. Yale later used visual signals, including adjustments of the captain's knit hat, to call plays. Centers could also signal plays based on the alignment of the ball before the snap. In 1888, however, Princeton Tigers football, Princeton University began to have its quarterback call plays using number signals. That system caught on and quarterbacks began to act as directors and organizers of offensive play. Early on, quarterbacks were used in a variety of formations. Harvard's team put seven men on the line of scrimmage, with three halfback (American football), halfbacks who alternated at quarterback and a lone fullback (American football), fullback. Princeton put six men on the line and had one designated quarterback, while Yale used seven linemen, one quarterback and two halfbacks who lined up on either side of the fullback. This was the origin of the T-formation, an offensive set that remained in use for many decades afterward and gained popularity in professional football starting in the 1930s. In 1906, the forward pass was legalized in American football; Canadian football did not adopt the forward pass until 1929. Despite the legalization of the forward pass, the most popular formations of the early 20th century focused mostly on the rushing game. The single-wing formation, a run-oriented offensive set, was invented by football coach Pop Warner, Glenn "Pop" Warner around the year 1908. In the single-wing, the quarterback was positioned behind the line of scrimmage and was flanked by a Halfback (American football), tailback, fullback (American football), fullback and wingback (American football), wingback. He served largely as a Blocking (American football), blocking back; the tailback typically took the snap, either running forward with the ball or making a lateral pass to one of the other players in the backfield. The quarterback's job was usually to make blocks upfield to help the tailback or fullback gain yards. Passing plays were rare in the single-wing, an unbalanced power formation where four linemen lined up to one side of the center and two lined up to the other. The tailback was the focus of the offense, and was often a triple-threat man who would either pass, run or kick the ball. Offensive playcalling continued to focus on rush (gridiron football), rushing up through the 1920s, when professional leagues began to challenge the popularity of college football. In the early days of the professional

(NFL), which was founded in 1920, games were largely low-scoring affairs. Two-thirds of all games in the 1920s were shutouts, and quarterbacks/tailbacks usually passed only out of desperation. In addition to a reluctance to risk turnovers by passing, various rules existed that limited the effectiveness of the forward pass: passers were required to drop back five yards behind the line of scrimmage before they could attempt a pass, and incomplete passes in the end zone resulted in a change of possession and a touchback. Additionally, the rules required the ball to be snapped from the location on the field where it was ruled dead; if a play ended with a player going out of bounds, the center had to snap the ball from the sideline, an awkward place to start a play. Despite these constraints, player-coach Curly Lambeau of the

, along with several other NFL figures of his era, was a consistent proponent of the forward pass. The Packers found success in the 1920s and 1930s using variations on the single-wing that emphasized the passing game. Packers quarterback Red Dunn and New York Giants and Brooklyn Dodgers (NFL), Brooklyn Dodgers quarterback Benny Friedman were the leading passers of their era, but passing remained a relative rarity among other teams; between 1920 and 1932, there were three times as many running plays as there were passing plays. Early NFL quarterbacks typically were responsible for calling the team's offensive plays with signals before the snap. The use of the

to call plays originated with Stagg in 1896, but only began to be used regularly in college games in 1921. In the NFL, players were typically assigned numbers, as were the gaps between offensive linemen. One player, usually the quarterback, would call signals indicating which player was to run the ball and which gap he would run toward. Playcalling (or any other kind of coaching from the sidelines) was not permitted during this period, leaving the quarterback to devise the offensive strategy (often, the quarterback doubled as head coach during this era). Substitutions were limited and quarterbacks often played on both offense and defense. The period between 1933 and 1945 was marked by numerous changes for the quarterback position. The rule requiring a quarterback/tailback to be five yards behind the line of scrimmage to pass was abolished, and hash marks were added to the field that established a limited zone between which the ball was placed before snaps, making offensive formations more flexible. Additionally, incomplete passes in the end zone were no longer counted as turnovers and touchbacks. The single-wing continued to be in wide use throughout this, and a number of forward-passing tailbacks became stars, including Sammy Baugh of the Washington Redskins. In 1939, Chicago Maroons football, University of Chicago head football coach Clark Shaughnessy made modifications to the T-formation, a formation that put the quarterback behind the center and had him receive the snap directly. Shaughnessy altered the formation by having the linemen be spaced further apart, and he began having players go in motion behind the line of scrimmage before the snap to confuse defenses. These changes were picked up by

coach George Halas, a close friend of Shaughnessy, and they quickly caught on in the professional ranks. Utilizing the T-formation and led by quarterback Sid Luckman, the Bears reached the 1940 NFL Championship Game, NFL championship game in 1940 and beat the Redskins by a score of 73–0. The blowout led other teams across the league to adopt variations on the T-formation, including the Philadelphia Eagles, Cleveland Rams and Detroit Lions. Baugh and the Redskins converted to the T-formation and continued to succeed. Thanks in part to the emergence of the T-formation and changes in the rulebooks to liberalize the passing game, passing from the quarterback position became more common in the 1940s and as teams switched to the T-formation, passing tailbacks, such as Sammy Baugh, would line up as quarterbacks instead. Over the course of the decade, passing yards began to exceed rushing yards for the first time in the history of football. The Cleveland Browns of the late 1940s in the All-America Football Conference (AAFC), a professional league created to challenge the NFL, were one of the teams of that era that relied most on passing. Quarterback Otto Graham helped the Browns win four AAFC championships in the late 1940s in head coach Paul Brown's T-formation offense, which emphasized precision timing passes. Cleveland, along with several other AAFC teams, was absorbed by the NFL in 1950 after the dissolution of the AAFC that same year. By the end of the 1940s, all NFL teams aside from the Pittsburgh Steelers used the T-formation as their primary offensive formation. As late as the 1960s, running plays occurred more frequently than passes. NFL quarterback Milt Plum later stated that during his career (1957–1969) passes typically only occurred on third downs and sometimes on first downs. Quarterbacks only increased in importance as rules changed to favor passing and higher scoring and as football gained popularity on television after the 1958 NFL Championship Game, often referred to as "The Greatest Game Ever Played". Early modern offenses evolved around the quarterback as a passing threat, boosted by rules changes in 1978 and 1979 that made it a penalty for defensive backs to interfere with receivers downfield and allowed offensive linemen to pass-block using their arms and open hands; the rules had limited them to blocking with their hands held to their chests. Average passing yards per game rose from 283.3 in 1977 to 408.7 in 1979. The NFL continues to be a pass-heavy league, in part due to further rule changes that prescribed harsher penalties for hitting the quarterback and for hitting defenseless receivers as they awaited passes. Passing in wide-open offenses has also been an emphasis at the high school and college levels, and professional coaches have devised schemes to fit the talents of new generations of quarterbacks. While quarterbacks and team captains usually called plays in football's early years, today coaches often decide which plays the offense will run. Some teams use an offensive coordinator, an assistant coach whose duties include offensive game-planning and often play-calling. In the NFL, coaches are allowed to communicate with quarterbacks and call plays using audio equipment built into the player's helmet. Quarterbacks are allowed to hear, but not talk to, their coaches until there are fifteen seconds left on the play clock. Once the quarterback receives the call, he may relay it to other players via signals or in a

Throughout football history, the racial make-up of quarterbacks did not reflect the racial makeup of the sport. Black quarterbacks especially faced barriers in breaking into the starting job at the highest levels. Professional football's first black starting quarterback came in 1968, when the American Football League's

after the AFL-NFL merger, and later started games for the Los Angeles Rams. Other early NFL black starting quarterbacks include Joe Gilliam of the Pittsburgh Steelers, who was the first black quarterback to start a season for any NFL team; though he was later benched after the first six games. The Giants were the last team fielded a black starting QB during an NFL season. During the 2013 NFL season, 67 percent of NFL players were African American yet only 17 percent of quarterbacks were; 82 percent of quarterbacks were white, with just one percent of quarterbacks from other races. In 2017, the New York Giants benched longtime starter Eli Manning in favor of Geno Smith, who was declared the starter.
