What Is A Sack In Football? Explained

In the football world, where competition is high, a quarterback serves as the main playmaker for his team. However, another factor in this equation is the sack. Commonly seen as a mere loss of yards after tackling an opponent behind the line of scrimmage, it has great strategic implications for any match and may potentially change its outcome. Let’s delve deeper into sacks by examining their definition, their impact on games, and their recording process.

What Is A Sack In Football? Explained

What Exactly is a Sack?

This happens when a defensive player tackles the quarterback behind the line of scrimmage before he can throw the ball away, having dropped back to pass. This is called a sack! It disrupts an offensive mission by forcing the quarterback to abandon his passing attempt, potentially causing him to lose some valuable yardage.

But why are sacks so important?

  • Disrupting Rhythm: In other words, sacks put paid to many coaches’ plans and designs on offense. The signal caller gives up possession of the ball prematurely which could result in losing ground or even cause turning over possession.
  • Field Position Advantage: Usually offenses are set back by a sack, putting them in a worse starting state for the next play. It makes throws riskier or less likely to lead to first downs.

The Evolution of Sacks Statistics:

Surprisingly enough, sacks were not always counted as an official statistic in football. It was only during the 1982 season that the National Football League started recording such actions, making it possible to assess defenses differently.

Demystifying Sack Recording: How Referees See It

So what makes up a few crucial elements that determine whether a play constitutes a sack? Here’s an explanation:

  • The Crucial Line: This dividing line within any game action is called the line of scrimmage, and if, after attempting a forward pass, the QB gets tackled behind it, then it means that there has been a sack.
  • Intention Matters: When the intended plan on that given play is for the quarterback to run with the ball, then if he is tackled behind the line of scrimmage, it is not a sack but a tackle for loss. When determining whether plays are sacks or tackles for losses, statisticians assess the intended play design and intentions of passing QBs.
  • Teamwork Makes the Dream Work: It may seem like one guy got to the quarterback first, but chances are that many individuals had a hand in taking down his opponent. The presence of several defenders causing pressure can make a quarterback escape with difficulty and eventually land on the field. Based on what each did in contributing to such play, sacks are awarded to one or many defenders.

Examples of Sacks in Action:

  • The Classic Drop Back Sack: linebacker blitzes past offensive linemen while a traditional drop back enables passers to lose yardage.
  • The Coverage Sack: Waiting for receivers to get open, this QB takes too much time before throwing away his football. The defense collapses, and an individual from its lines takes him down before he makes any move.
  • The Screen Gone Wrong: In this instance, a defensive tackle blows up the play by attacking the QB as they attempt to carry out their screen pass, getting the running back involved almost immediately from center field for negative yards.

The Ripple Effect: How Sacks Impact the Game

Sacks do not happen in isolation; instead, they highly influence how games proceed. Here are some key effects:

  • Momentum Swing: The right sack at the right time can completely change a drive’s momentum, costing the offense precious yards and providing the defense with an emotional boost that can transform what seemed to be a productive offensive series into a frustrating punt.
  • Field Position Advantage: As mentioned before, sacks force offenses backward, pushing them to punt from farther away. This gives their opponents a good field position to start their next drive.
  • Psychological Impact: Quarterbacks and their entire offenses can also be discouraged from making sacks, which come about from being under constant pressure. Rushed throws, interceptions, or anxiety are all indicators of feeling out of control.

Blitzing Their Way To Glory: Defensive Schemes for Sacks

Nobody accidentally makes a sack; defensive coordinators develop elaborate strategies to pressure quarterbacks. These include some popular ones:

  • The Four-Man Rush: This traditional approach involves defenders in the front line overpowering offensive linemen using strength and speed to reach the quarterback. During the “Steel Curtain” era, teams like the Pittsburgh Steelers became perfect at using this method.
  • The Blitz: In this case, additional defenders (linebackers or safeties) rush towards the quarterback, often faking snaps before they confuse the offensive line. Aggressive blitzes were used by the Seattle Seahawks “Legion of Boom” defense in humiliating their rivals.
  • Stunting: This tactic confuses players along the line of scrimmage by having d-linemen change positions pre-snap. A well-executed stunt allows for free rushing, which could result in a sack opportunity.

Mastering The Craft: Key Techniques for Sack Artists

Schemes aside, individual brilliance is paramount when it comes to getting sacks. Here are some important techniques that defensive players use to achieve this goal:

  • Speed Rush: Beating an offensive tackle with explosive speed and agility before they have time to set up their block is known as a speed rush. Think about Lawrence Taylor, who was synonymous with relentless speed rushes that constantly tormented quarterbacks.
  • Power Rush: Using brute strength and leverage to outmaneuver an offensive lineman and charge straight up the field towards the quarterback. Players like Aaron Donald are known for their power rush.
  • Hand Technique: The ability to control your hand and knock off a blocker’s hand is vital in allowing you space as well as disturbing the throw of the quarterback. People have praised JJ Watt for possessing some of the finest hand techniques in history.

When Strategies Collide: Iconic Sack Moments

Sacks can change momentum, creating lasting memories in football history. Here are a few unforgettable samples:

  • Super Bowl XLII: With seconds left and the game tied, the New York Giants’ Eli Manning escapes from a collapsing pocket to complete a miraculous catch by David Tyree. Nevertheless, on the next play, Michael Strahan sacked Manning, leading to a victory for the Giants.
  • Super Bowl 51: With the New England Patriots trailing by one point late in the fourth quarter, Dont’a Hightower of the Atlanta Falcons brought down Tom Brady, causing Brady to fumble the ball away and ultimately leading his team to an incredible comeback.

The Sacks Stand Tall: Records and Renowned Pass Rushers

In professional football, sacks are a currency that means something. We’ll look at some sack leaders and well-known pass rushers:

  • All-Time Sack Leaders: Bruce Smith leads them all with 200 career sacks, followed closely by Reggie White and Deacon Jones.
  • Sack Specialists: Football players such as Derrick Thomas or Khalil Mack were known for their uncanny ability to pressure quarterbacks and get sacks, making them feared league-wide.

The Analytics Of The Sacks

Sacks are more than just box-score statistics; advanced analytics go further.

  • Pressure Rate: This metric surpasses sacks as it accounts for all instances where the quarterback has to throw under pressure.
  • Win Rate: There is a strong correlation between winning games and getting sacks. Consistent pressure on the quarterback leads to better winning records for teams.
  • Contract Negotiations: Sacks are an important factor in player contracts. Players with high numbers of sacks can command top dollars, which is indicative of their worth in disrupting opposing teams’ offenses.


A sack is a curse word for quarterbacks; they serve as constant reminders of the pressure they face from their opponents behind the line of scrimmage. Knowing about sacks’ strategies, techniques, and historical importance makes one appreciate the chess game between offense and defense more.
