Why Do Football Players Say Blue 42?

If you’ve ever watched a game of American football, you may have heard the quarterback yelling out phrases like “Blue 42” before the ball is snapped. It’s a common occurrence on the field, but have you ever wondered why they say those specific words? In this article, we will dive into the origins of the phrase “Blue 42” and explore the fascinating world of audible calls in American football.

Early History of Football Signals

To understand the significance of “Blue 42,” we must first explore the early history of football signals. Communication between players on the field has always been crucial in football, but it wasn’t until the early 20th century that teams started using hand signals and codes. These signals were primarily used to convey plays and strategies without the opposing team understanding.

Evolution of Audible Calls in American Football

As the game of football evolved, so did the need for more complex and precise communication on the field. The introduction of audible calls allowed the quarterback to change or adjust the play at the last moment based on the defensive alignment. This gave the offense a tactical advantage by exploiting the weaknesses of the defense.

The Introduction of Blue 42

Now, let’s focus on the specific phrase “Blue 42.” Decoding the components of this audible call will give us a deeper understanding of its meaning. The use of colors in audible calls is a common practice in American football, as it allows for quick and efficient communication among teammates. “Blue” is one such color that is often used to signal a change in the play or formation.

The number “42” in “Blue 42” is a unique identifier for the specific play or adjustment being made. Each team has its own playbook, and within that playbook, plays and adjustments are assigned different numbers. The number 42 could represent a specific route combination, a blocking scheme, or even the direction in which the quarterback plans to throw the ball.

Common Audible Calls in American Football

While “Blue 42” is one of the more well-known audible calls, there are many other color-coded audible calls used in American football. Some examples include “Red 80,” “Green 20,” and “White 60.” These calls all serve the same purpose – to change or adjust the play based on the defensive alignment.

In addition to colors, numbers play a significant role in audible calls. Quarterbacks often use numbers to signal specific adjustments or routes to their receivers. For example, “Hot route 7” might indicate that the receiver should run a quick slant route, while “9 route” could mean a deep go route down the field.

Variations of “Blue 42” can also be used to confuse the defense. The offense may use “Blue 43” or “Blue 41” to make the defense second-guess their initial alignment and create a more favorable matchup for the offense.

The Role of Communication in Football

Effective communication is crucial in any team sport, and football is no exception. In American football, non-verbal communication plays a significant role in conveying information quickly and discreetly. Hand signals, facial expressions, and even a subtle nod can all be used to communicate on the field.

To enhance communication, teams often employ communication systems such as radio helmets. These helmets allow the coaching staff to relay play calls directly to the quarterback’s earpiece, eliminating the need for verbal communication and minimizing the risk of the opposing team intercepting the call.

Strategies and Tactics in Audible Calls

Audible calls provide quarterbacks and offenses with a range of strategic options. One common tactic is misdirection, where the quarterback intentionally makes the defense think the play is going in one direction but quickly changes it to exploit a weakness in the opposing defense.

Audible calls also allow offenses to capitalize on defensive weaknesses. If the quarterback sees that the defense is weak against the run, they may change the play to a running play. Conversely, if the defense is giving too much cushion to the receivers, the quarterback may opt for a quick pass to exploit the open space.

Additionally, audible calls allow teams to adapt to changing game situations. If the offense recognizes that the defense is anticipating a certain play, they can quickly adjust to a different play to keep the defense guessing and maintain an element of surprise.

Training and Preparation for Audible Calls

Quarterbacks undergo extensive training to master audible calls. They must study their own game film as well as the film of their opponents to understand defensive alignments and tendencies. Repetition and practice are key in ensuring that the quarterback and the rest of the offense are on the same page when it comes to executing audible calls.

Film study also plays a significant role in helping quarterbacks decipher defensive alignments and make quick decisions. By analyzing the movements and positioning of the defensive players, quarterbacks can identify potential weaknesses and adjust the play accordingly.

The Evolution of Audible Calls in Football

Over the years, there have been numerous innovations in audible strategies. Advances in technology, such as radio helmets and video analysis software, have significantly enhanced communication and preparation on the field.

Audible calls have also had an impact on the tempo and dynamic of the game. They allow offenses to control the pace of play and keep the defense off-balance by constantly changing the play at the line of scrimmage.

Looking ahead, the future of audible calls in football is promising. As technology continues to advance, we can expect even more sophisticated communication systems and strategies to be implemented, further enhancing the game.

The Language and Terminology of American Football

American football has its own unique vocabulary and terminology. Understanding the language of the game is essential for all football players and fans. Terms like “touchdown,” “quarterback,” “linebacker,” “Super Bowl,” and “playoffs” are all part of the football lexicon.

It’s important to note that American football should not be confused with soccer or association football, as the terminology and rules are vastly different. Instead of “FIFA” and “World Cup,” the NFL and Super Bowl are the primary governing bodies and championships in American football.


In conclusion, the phrase “Blue 42” is just one example of the many audible calls used in American football. It is a product of the game’s evolution and the need for effective communication on the field. Audible calls not only allow quarterbacks to adjust plays based on the defensive alignment but also serve as a strategic tool to exploit weaknesses and adapt to changing game situations.

The use of colors and numbers in audible calls adds another layer of complexity and efficiency to the communication process. Understanding the language and terminology of American football is essential in appreciating the significance of these audible calls.

As the game continues to evolve, we can expect the importance of audible calls to become even greater. They not only enhance communication but also shape the game’s tempo, dynamic, and overall strategy. So the next time you hear a quarterback shout “Blue 42,” remember that it represents years of innovation, strategy, and teamwork in the fascinating world of American football.
