The History of the Playbook

By 4Football Staff · November 4, 2026 · 11 min read

From captains calling plays by instinct to binders, wristbands and tablets, here is how football teams learned to write down, teach and communicate their plays.

Today a professional quarterback may be expected to know hundreds of plays, along with the formations, motions, protections and audibles that go with them. A first-year player gets a thick set of pages, now often on a tablet, and a coach who expects him to learn it by the time the season starts. The playbook feels like a basic fixture of the sport.

It was not always there. In the first decades of American football, there was nothing to hold, because there was very little to write down. The playbook grew out of a long series of changes: bigger rosters, more complicated formations, the forward pass, film, radios and, finally, the screen. This article follows the story from the sandlot to the tablet.

Before the playbook: captains and signals

In the earliest years of the sport, teams were run by their players. A captain on the field decided what the team would do next, often using a shouted code or a short signal to tell teammates where the ball would go. There were few formations to remember and few specialized roles. A play was less a designed sequence than a general plan: push here, run there, kick when stuck.

As the rules grew more elaborate in the late nineteenth century, teams began to pay attention to coordination. Coaches, many of them former players, were becoming a permanent part of college football, and they began to design plays on paper and in practice. Walter Camp, the Yale figure whose rule changes shaped the early game, is the best-known example of someone who treated football as a problem to be solved by design rather than left to chance.

The huddle

One piece of equipment in every playbook is the huddle, the circle that teams form between plays. The best-documented account of its origin comes from Gallaudet University, a school for the deaf in Washington, D.C. Players there communicated in sign language, and a quarterback named Paul Hubbard is credited with having gathered his teammates in a circle in the 1890s so that opponents could not see their signs. The practice spread, because any team with a secret to protect had a reason to copy it. The huddle did not become universal overnight, but over time it became the standard way to communicate the next play.

The huddle gave teams a new constraint. A play had to be short enough to be told to eleven people in the time allowed, which pushed coaches to create short verbal codes and numbering systems.

Wedges, boxes and the systems of the early coaches

The early coaching stars were known for their systems, and the systems were the first things we could fairly call playbooks.

• Mass formations. In the 1890s, offenses used tightly packed formations that moved a mass of players forward together. The flying wedge, which was introduced at Harvard in the early 1890s, was among the best-known examples. The violence of these formations contributed to the safety crisis, and many of the sport's early rule changes were aimed at making the game less dangerous.
• The single wing and double wing. Glenn "Pop" Warner, who coached at Carlisle and other schools, was one of the main developers of the wing formations, in which a back lined up outside the end and the ball was snapped some distance to a tailback. The single wing and its variants would be the dominant professional and college offense for decades.
• The Notre Dame Box. Knute Rockne's Notre Dame teams of the 1920s used a backfield arrangement known as the box, with a shifting motion before the snap that put the defense on its heels. Rockne's system relied on timing and rhythm among the backs, and it was part of a style that shaped how coaches taught their teams for years.

What these systems had in common is that they were taught, not just drawn. The coach worked out the plays, then drilled them on the practice field until the timing was automatic. The playbook, in this period, was mostly in the coach's head and in the players' habits.

Numbering the holes

By the early and middle twentieth century, coaches needed a shorthand for where a running play would go. A common solution was to number the gaps in the offensive line, so that a play call included both the ball carrier and the hole he was to hit. Numbering conventions vary from team to team and level to level, which is why a call that means one thing in one program can mean something different in another. The idea of using numbers to name parts of a play remains in the game today in the form of route trees and blocking schemes.

The T formation and the modern playbook

The change that pushed the playbook into something we would recognize came in the 1930s and 1940s with the rise of the T formation. In the T, the quarterback lines up directly behind the center, takes the snap, and hands off or passes to backs lined up behind him. The formation required a more intelligent quarterback and more complicated timing, and it opened the way for a larger variety of plays. A coach could now combine handoffs, fakes, and passes in a single set of actions.

The story of how the T became the dominant formation, with Clark Shaughnessy, George Halas and the Chicago Bears at its center, is told in our T formation article. For the playbook, the important point is that the T made plays more complex, and complexity requires documentation. A coach who wanted to teach many plays had to write them down.

Paul Brown and the classroom

If there is a single figure most associated with the idea that football should be taught like a school subject, it is Paul Brown. He coached at the high school, college and professional levels, and at each stop he was known for treating football as something to be studied. Players at his teams were expected to keep notebooks, attend meetings, and take tests. Plays were diagrammed, installed in classroom sessions, and reviewed by the staff.

Brown also experimented with how plays reached the field. In his era the quarterback was largely responsible for calling plays, but Brown was one of the coaches who wanted to control the call himself. One of his methods was the messenger: a substitute, often a guard, who was sent in with the next play. That approach led to later experiments with sideline signals and, eventually, radios. His wider legacy included film study, scouting reports and a system of assistant coaches who each had a specialty, which is part of the staffing structure we see across football today.

The core idea Brown helped normalize is that a team is only as good as what its players can retain, so the coach's job includes teaching in a way that sticks.

Scripts, systems and terminology

By the 1960s and 1970s, the playbook had grown into a thick volume at the pro level, and several coaches became known for the way they organized it.

Vince Lombardi and the power sweep

Vince Lombardi's Green Bay Packers are remembered for having a small number of core plays that they practiced until they were nearly perfect. The power sweep, in which the guards pulled to lead the ball carrier around the edge, was the signature example. Lombardi's approach is often described as the opposite of the huge-playbook model: teach less, but teach it deeper. That tension, between a large menu of plays and a small one executed well, is still a live argument among coaches.

Bill Walsh and the script

Bill Walsh, who built the San Francisco 49ers' offense in the late 1970s and 1980s, was known for planning the start of a game in advance. His practice of scripting the first group of offensive plays, which coaches typically describe as the first fifteen or so, meant that the play-caller did not need to improvise early. The script allowed the staff to test how the defense reacted to specific looks. Scripting spread across football, and it is now a standard part of game planning at the professional and college levels.

Walsh's offense is the model for what is often called the West Coast offense, which we explain in our article on that system. Its terminology tended to be descriptive and long, with a call that named the formation, the protection and the routes in sequence.

Concept-based naming

A different philosophy of naming plays emerged in other systems. In the approach associated with Ron Erhardt and Ray Perkins, who worked with the New England Patriots in the 1970s and early 1980s, play calls were organized around concepts, with each name standing for a specific idea and set of assignments. A short word could carry a large amount of information, because the team had agreed on what it meant. The advantage was that the call itself could be short, which helps in a hurry-up situation. Today, both styles influence how teams name their plays, and you can find hybrids at every level.

Technology changes the playbook

Film

Film changed how plays were created and studied. Before film, a coach relied on memory and on assistants who watched from the stands. Once game film became standard, a coach could see exactly what a defender did on a particular snap, count the steps of a receiver's route and design counters. The playbook became something that was revised after every opponent. Film work is still central to preparation.

Radios and sideline communication

The next big change was how to get a play from the coach to the quarterback. Teams used a range of approaches: messengers, hand signals, and signboards. In the 1950s, a professional team experimented with a radio in a quarterback's helmet, but the league prohibited it. In 1994, the NFL approved a system in which one offensive player and one defensive player on each team may wear a radio receiver in the helmet, with the signal cut off just before the snap, so that a coach could send the play directly to a quarterback. Because details like timing and the number of players have changed over the years, check the league's current rules for the specifics. The effect was a major change in how play-calling works: the coach in the booth or on the sideline could now talk directly to the player who lined up under center, and the quarterback was less likely to be the sole caller.

At the college level, helmet radios for offensive and defensive players have been a more recent development, and rules about them have shifted in recent years, so check with the governing body if you need the current position. In the meantime, college offenses developed signboards with pictures and symbols that a coach displays so that players can read the call from the sideline. These boards became popular with fast-moving offenses that wanted to run plays without a huddle.

The history of the sideline systems themselves, from the wristband to the headset, is the subject of our coaching article on game day communication.

Wristbands and play sheets

Players can carry plays in their heads, but in a complex offense they often carry them on their arms. Many quarterbacks wear a wristband with a grid of play numbers or symbols, and a coach calls a number that corresponds to a play on the band. Coaches use laminated play sheets, arranged by down and distance, to decide what to call. This is an old technology compared to tablets, but it remains valuable because it works when batteries do not.

Tablets and digital playbooks

In recent years, teams have moved playbooks onto tablets and laptops. A digital playbook can include animated plays, video clips, quizzes and personalized assignments. Players can study on their own time, and a coach can update the install as quickly as he edits a file. The league itself introduced tablets on the sideline to replace printed photographs of formations. The change did not alter the underlying idea, which is the same one Paul Brown pursued with notebooks and tests: a team must know its plays better than the opponent does.

The tablet also raised new questions about security. Because a playbook is a competitive document, teams treat it carefully. Teams typically collect playbooks from players who are released, and digital versions can be locked.

Stolen signals and secrecy

The more teams relied on signals, the more teams tried to steal them. Defenses have long tried to decode an offense's signs, and offenses have long used code words, dummy signals and changing signals to defeat decoders. In 2007 the NFL disciplined the New England Patriots for videotaping opposing coaches' signals in violation of league rules. The incident led the league to clarify its rules on video and signal-stealing. It is a reminder that the playbook is only one side of the issue; the other is the means of communication.

What the playbook looks like at different levels

Not every team has a thick book. The size of a playbook usually depends on the age and experience of the players.

If you coach or play at a recreational level, the lesson of the history is a simple one: start small, teach thoroughly, and add only when the players have mastered what is already there. The Play section has resources for recreational leagues, and the coaching articles on this site, including how to design a playbook from scratch, cover the practical steps.

Why the history matters

The development of the playbook shows how closely football's rules, technology and strategy are linked. Rules that allowed the forward pass created more complex offenses. More complex offenses required more complete teaching. Better teaching and better film required better communication. Each step pushed the game to a higher level of detail.

The next time you watch a game and see a quarterback glance at a wristband, a coach hold up a signboard or a play-caller check a laminated sheet, you are seeing the result of that long process. For a look at how teams use their schedules and rosters to prepare, see the team pages and the schedule.

The short version

• Early football teams were run by captains who called plays on instinct; the playbook came later, as formations grew more complex.
• The huddle is traditionally linked to Gallaudet University in the 1890s, where deaf players needed to hide their signs.
• Coaches such as Pop Warner and Knute Rockne built named systems; the T formation of the 1930s and 1940s pushed teams toward larger, written playbooks.
• Paul Brown helped make football a classroom subject, with notebooks, tests and sideline-sent plays.
• Scripting, concept-based naming and film study shaped how modern teams organize their calls.
• Radios, signboards, wristbands and tablets are different answers to the same question: how to get a play to eleven players quickly and secretly.
