The Art of the Script: How NFL Coaches Plan Their First 15 Plays

The opening kickoff soars, the crowd roars, and the meticulously crafted plan is set in motion. In the high-stakes world of the NFL, the first 15 plays are more than just a sequence; they’re a calculated strategy, a chess match within a war. Like Bill Belichick and his staff who put together sound game plans week after week, coaches dedicate countless hours to dissecting film, identifying weaknesses, and scripting the perfect start. But what exactly goes into this “script,” and why is it so crucial?

The Genesis of the “First 15”

The concept of scripting the opening plays is often credited to the late Bill Walsh, the Hall of Fame coach of the San Francisco 49ers. Walsh, known for his meticulous preparation and innovative offensive schemes, recognized the value of dictating the early tempo and gaining a strategic advantage. The “First 15,” as it became known, wasn’t just a random collection of plays; it was a carefully curated sequence designed to test the defense, exploit matchups, and establish the offense’s rhythm.

Steve Young recalled that the scripts were more about the 49ers than the opponent. It was rare for the 49ers to get all the way through the scripted First 15. “Its primary purpose was to put people on notice the night before — ‘This is what we’re doing. This is where we’re headed. These are the things we’re going to be dialing up,’ ” he said.

Why Script at All?

In today’s NFL, where defensive schemes are increasingly complex and adaptable, scripting the first 15 plays offers several key advantages:

Information Gathering: The initial script allows offensive coordinators to gather valuable data on the defense’s tendencies, alignments, and personnel groupings. By observing how the defense reacts to different formations and play calls, coaches can identify potential mismatches and adjust their game plan accordingly.
Exploiting Weaknesses: The script provides an opportunity to attack specific weaknesses identified during film study. Whether it’s targeting a vulnerable cornerback with Stefon Diggs or exploiting a slow-footed linebacker with a quick running back, the first 15 plays can be tailored to maximize the offense’s strengths against the defense’s liabilities.
Setting the Tone: A fast start can inject confidence into the offense and put pressure on the opposing team. By executing a series of successful plays early on, the offense can establish its dominance and dictate the flow of the game.
Building Confidence: Scripted plays are meant to build confidence, attack defensive weaknesses, and give the offense information about how the defense is treating specific looks to start the game.
Creating a Rhythm: The script allows the quarterback and offensive unit to get into a rhythm early in the game. By running a predetermined sequence of plays, they can develop a sense of timing and cohesion, which can translate into improved execution as the game progresses.

The Modern Script: A Blend of Art and Science

While the core principles of scripting remain the same, the modern NFL script has evolved to incorporate advanced analytics and a deeper understanding of defensive strategies. Offensive coordinators now use sophisticated data to identify the most effective play combinations and predict defensive responses.

Kyle Shanahan enters the 2025 season still firmly entrenched as the standard for offensive play-callers in the NFL. San Francisco may have fallen short of the playoffs last year, but Shanahan’s offense still finished 11th in EPA per play despite injuries to key players. Once defined by play-action boots and stretch-zone runs, the “Shanahan offense” has become more of a myth than a fixed identity. The 2024 version of San Francisco’s attack featured a noticeable drop in play-action usage, instead leaning into intermediate and vertical concepts that opened up the field in new ways. That adaptability is what makes Shanahan unmatched. He’s not just calling plays—he’s constructing a system like an architect, shaping each detail to fit his personnel.

Here’s a glimpse into the elements that might be included in a contemporary NFL script:

Formation Variety: The script often features a mix of formations, including shotgun, pistol, and under-center looks, to test the defense’s versatility and identify any communication breakdowns.
Run-Pass Balance: While some teams may lean heavily towards the run or pass early on, most scripts incorporate a balanced approach to keep the defense guessing. This can involve mixing inside runs with outside runs, short passes with deep throws, and play-action passes with designed quarterback runs.
Personnel Groupings: The script may utilize different personnel groupings, such as 11 personnel (1 running back, 1 tight end, 3 wide receivers) or 12 personnel (1 running back, 2 tight ends, 2 wide receivers), to create favorable matchups and exploit defensive weaknesses.
Tempo Changes: Some offensive coordinators like to incorporate tempo changes into their scripts, alternating between a fast-paced, no-huddle attack and a more deliberate, methodical approach. This can disrupt the defense’s rhythm and force them to make quick decisions.
Specific Play Concepts: The script will typically include a variety of play concepts, such as zone runs, power runs, screen passes, crossing routes, and deep shots, to test the defense’s ability to defend different types of plays.

Adapting on the Fly

While the script provides a roadmap for the opening series, coaches must also be prepared to adapt on the fly. Defenses can throw unexpected looks, injuries can occur, and the game situation can change in an instant. As Brian Billick said, “The concept of scripting your opening 15 is not literally: We’re just going to run these 15 plays, hell or high water.”

Smart coaches use the script as a starting point, but they remain flexible and adjust their play calling based on the unfolding circumstances of the game. This requires a deep understanding of the game, a keen eye for detail, and the ability to make quick decisions under pressure.

The Art of Deception

In addition to gathering information and exploiting weaknesses, the first 15 plays can also be used to deceive the opposing team. Coaches may include plays that are designed to set up a future attack or create a false sense of security.

For example, an offensive coordinator might run a series of short passes early in the game to lull the defense into a false sense of security. Then, later in the game, they can unleash a deep pass to exploit the defense’s overconfidence.

The Future of the Script

As the NFL continues to evolve, the art of the script will likely become even more sophisticated. With the rise of advanced analytics and the increasing emphasis on offensive innovation, coaches will continue to find new and creative ways to gain an edge in the opening series.

Whether it’s using virtual reality to simulate game situations or incorporating artificial intelligence to predict defensive tendencies, the future of the script is bound to be filled with exciting new possibilities.

The opening 15 plays represent a critical juncture in the game, a moment where meticulous planning meets real-time execution. By understanding the art and science behind the script, fans can gain a deeper appreciation for the strategic complexities of the NFL and the chess match that unfolds on every snap.
