Defensive success rates tell a story that Vita Vea’s box score couldn’t capture on January 24, 2021. The temperature at Lambeau Field sat at 29 degrees, and the Tampa Bay Buccaneers’ nose tackle was returning from a fractured ankle that had sidelined him for 15 weeks. Across the line, Green Bay’s offensive linemen faced a miserable assignment: move a 300-plus-pound defender who could wreck the blocking scheme without ever reaching the quarterback.
Vea played 33 defensive snaps that afternoon without recording an official defensive statistic. Tampa Bay still sacked Aaron Rodgers five times, won 31-26 and advanced to Super Bowl LV. The Buccaneers’ senior writer Scott Smith later explained how Vea occupied blockers and helped Shaquil Barrett and Jason Pierre-Paul find favorable matchups. His work barely registered in the box score, but Green Bay’s offensive line had to account for him.
That invisible contribution raises a question NFL front offices must answer every offseason. How much should a team pay for a defender who rarely finishes the play but repeatedly determines where the football can go? The answer begins with defensive success rates, a measure that exposes the hidden value of controlling the line of scrimmage.
Dexter Lawrence shows what a double team really costs
Watch Dexter Lawrence attack a center, and the first collision can look almost unfair. His hands strike the blocker’s chest, his feet keep driving, and the guard often arrives before the center can recover. Suddenly, the offense has committed two massive linemen to one defender. That second blocker carries the real cost.
On an inside-zone run, the center and guard typically work together before one climbs toward a linebacker. Lawrence can disrupt that timing simply by refusing to move. When the guard stays to help, the linebacker gets a cleaner path to the running back. New York built much of Lawrence’s reputation around that kind of interior control during his years with the Giants.
Pro Football Focus captured the attention Lawrence commanded in its 2024 study of defensive double-team rates. Through five weeks, Lawrence faced multiple blockers on 47 of his 72 run-defense snaps, a 65.3 percent double-team rate. Houston’s Folorunso Fatukasi led the same sample, facing two or more blockers on 64 of 89 snaps, or 71.9 percent.
Those percentages measure offensive attention, not automatic wins. A nose tackle can absorb two blockers and still surrender five yards. The difference comes from what happens after the initial collision. When Lawrence keeps his shoulders square and holds the line, the guard cannot reach the second level on schedule. The running back must commit to a narrower crease, while the linebacker gets room to attack.
The defender who makes the tackle receives the statistical reward. Lawrence may receive nothing, even though he forced the offense into its second-best option. That imbalance helps explain why defensive success rates matter. They shift attention from the player who finishes the collision to the defenders who make the stop possible.
Why a three-yard run can feel like a defensive victory
A nose tackle does not need to drive a running back backward to win his assignment. Sometimes, holding the offense to three yards changes the entire possession.
Pro Football Reference’s success-rate measure, explained by Jonah Gardner when Sports Reference introduced it in 2023, shows why raw rushing totals can misrepresent an effective play. Under that method, an offense needs at least 40 percent of the required yards on first down, 60 percent on second down and 100 percent on third or fourth down.
A four-yard gain on first-and-ten keeps the playbook wide open. That same gain on third-and-six sends the punt unit onto the field. Down and distance change the meaning of every yard, and a nose tackle can influence those outcomes without making the stop himself.
The effect becomes even clearer over an entire drive. Stuff a first-down run for one yard, and the offense faces second-and-nine. Hold the next carry to three yards, and the quarterback suddenly needs six yards through the air. A defense that consistently wins those early-down battles can dictate how an opponent attacks third down.
The difference between penetration and gap control
Consider a running back such as Saquon Barkley attacking a wide-zone front. The offensive line moves laterally, hoping to stretch the defense before Barkley plants his foot and attacks a crease. If the nose tackle gets knocked sideways, the running back can find a cutback lane. A strong interior defender forces the blocker to work harder before that opening appears.
Against duo, the challenge changes. Offensive linemen create vertical movement through double teams, and the running back reads the linebackers before choosing his lane. A nose tackle who refuses to retreat can disrupt that entire exchange. Both concepts demand different techniques from the defender, but neither requires him to make every tackle.
This distinction matters when interpreting defensive success rates. A tackle for loss attracts attention, but consistently denying the offense manageable second downs can prove equally valuable. An interior defender might record only three tackles while holding his ground against repeated double teams. If his linebackers consistently finish runs after two yards, his influence extends far beyond those three stops.
Now consider a penetrator who produces two spectacular tackles for loss but repeatedly abandons his assigned gap. His highlights look better, though his defense might not. Scouts must judge the entire assignment rather than the finish.
The Dexter Lawrence breakout data that exposed a statistical blind spot
Lawrence’s emergence during the 2022 NFL season offered an early warning about the limits of run-defense statistics. In an Opta Analyst study of his breakout season, Nicholas McGee uncovered an unusual contrast between Lawrence’s growing reputation and his production against the run.
Lawrence had a 20.3 percent run disruption rate, below the 23.1 percent average among qualifying interior defenders in Opta’s sample. His 49.2 percent run-block win rate barely exceeded the corresponding 49.0 percent league average. Those numbers appeared ordinary for a player whose physical dominance had become obvious on tape.
The explanation lay in his responsibilities. Opta found that Lawrence had aligned at nose tackle on 81 of his first 123 run-defense snaps. His job frequently required absorbing double teams and protecting linebackers rather than charging into the backfield.
By comparison, Aaron Donald often attacked gaps aggressively, trying to reach the runner before a blocking combination developed. Both approaches created value, but they produced different statistical profiles. A defender who occupies two blockers may create the same disruption as one who beats a guard cleanly, even though their individual grades tell different stories.
That Opta study belongs to Lawrence’s 2022 breakout period, not a current 2026 ranking. Its disruption and win-rate figures reflect that particular sample rather than today’s player grades. The broader point has survived: traditional measures cannot always distinguish a defender who loses his matchup from one who sacrifices an individual statistic to protect the scheme.
Lawrence’s value followed him to Cincinnati
Lawrence’s move from the Giants to the Cincinnati Bengals in April 2026 provided another example of the attention elite interior defenders command.
PFF analyst Mark Chichester highlighted his immediate impact in Cincinnati after the first two games of the 2026 season. Lawrence had earned a 91.0 overall defensive grade, leading all interior defenders in PFF’s early-season sample. Opponents also double-teamed him on 79.4 percent of his pass-rush snaps.
That figure measures pass protection, not run defense. It cannot be directly compared with his 65.3 percent run-defense double-team rate from 2024. Still, both snapshots reveal the same tactical problem for offensive coordinators. Lawrence demands extra blocking attention whether he attacks the quarterback or controls an interior rushing lane.
PFF’s early Cincinnati evaluation also gave Lawrence an 89.9 run-defense grade through two games. He produced three defensive stops on 21 run-defense snaps, and his three tackles came at an average depth of the line of scrimmage. The small sample did not establish a full-season trend, but it showed that his value extended beyond attracting pass-protection help.
When Lawrence ties up the center and guard while a linebacker shoots into the backfield, Cincinnati can turn an ordinary first down into a difficult second down. If teammates fail to fill their gaps, even his best individual work can disappear beneath a long run.
That leaves scouts with a familiar problem. Defensive success rates reveal whether an offense stayed on schedule, while individual grades show how a defender performed. Neither fully captures the guard who never reached his linebacker or the running back who abandoned his designed gap. For years, finding those answers meant grinding through film one snap at a time. New tracking technology is beginning to make that hidden work easier to measure.
Next Gen Stats finally gives the trenches their own spotlight
The NFL introduced a more detailed approach ahead of the 2026 season. Working with Amazon Web Services, the league’s Next Gen Stats analytics team developed new models designed to identify run concepts and individual blocking matchups. The September rollout addressed a longstanding problem: traditional rushing statistics tell us where the ball went, but not necessarily which blocker opened the lane or which defender closed it.
The new classification model recognizes 16 run-concept labels, including distinctions between man, zone and gap schemes. It also identifies the intended rushing gap and the lane the ball carrier actually attacks.
A companion run-blocking model tracks which defender an offensive lineman attempts to block, the type of block he executes and how long the engagement lasts. For nose tackles, those details offer a clearer picture of the work that disappears between the snap and the tackle.
Measuring the blocker who never reaches the linebacker
Picture a standard inside-zone run against a three-man defensive front. The center engages the nose tackle while the guard helps secure the interior before climbing toward the linebacker. The nose tackle refuses to give ground. His hands remain inside, his hips stay low, and the guard cannot release.
With the linebacker unblocked, the running back encounters contact before reaching the second level. Under traditional statistics, the linebacker collects the tackle. The nose tackle receives little recognition unless he also reaches the runner.
The newer Next Gen Stats models create a path toward identifying those contributions. They can track double-team involvement, engagement duration and defenders who disrupt rushing plays without receiving tackle credit.
The technology does not automatically prove how many points one nose tackle saves. Coaching assignments, opponent quality and help from teammates still complicate the picture. But scouts can ask sharper questions. How long does the defender occupy the center? Does the guard reach the linebacker? Does the running back abandon the designed gap because the interior closes?
Pair those answers with defensive success rates, and front offices get a clearer picture of how a lineman affects the entire defense. The goal is not to replace film study, but to give scouts better evidence for what they already recognize on tape.
Tampa Bay proved that stopping the run takes more than one giant
The Buccaneers’ 2020 championship defense provides an essential warning against giving a nose tackle too much individual credit.
In her postseason evaluation of Tampa Bay’s defensive line, Buccaneers writer Carmen Vitali highlighted a front that allowed a league-best 80.6 rushing yards per game and 3.43 yards per carry during the 2020 regular season.
That achievement becomes more impressive when considering Vea’s injury. He broke his ankle against Chicago in Week 5 and missed the remainder of the regular season. Tampa Bay still finished first in rushing yards allowed per game.
Ndamukong Suh, Will Gholston, Rakeem Nuñez-Roches and the rest of the defensive rotation helped sustain that performance. Behind them, linebackers Lavonte David and Devin White attacked rushing lanes with speed. The Buccaneers did not depend on one oversized defender to rescue every run play.
Defensive coordinator Todd Bowles constructed a front that allowed several players to fill different roles. Tampa Bay could shift alignments, threaten pressure and adjust its personnel without abandoning its commitment to controlling the interior.
Vea’s absence exposed the depth of that structure. His return made the unit more versatile, giving Bowles another powerful defender who could demand extra attention at the line.
Why Vea’s return changed the blocking equation
When Vea rejoined the Buccaneers for the NFC Championship Game, he did more than reinforce their interior run defense.
His size and power forced Green Bay to account for him in protection. That attention created chances for Barrett and Pierre-Paul to attack from the edges. The pair combined for all five Tampa Bay sacks in the victory over the Packers.
The effect continued against Kansas City in Super Bowl LV. Tampa Bay’s defensive-line review described how Bowles moved Vea and Suh into outside alignments while bringing his edge rushers inside. The shifting front complicated assignments for an already depleted Chiefs offensive line.
Kansas City finished with just nine points. Vea played 41 percent of Tampa Bay’s defensive snaps during the championship victory.
Those numbers do not establish that Vea alone decided the game. They show how Bowles incorporated a powerful interior presence into a flexible defensive plan, creating opportunities for teammates without relying on one player to make every stop.
For defensive success rates, the distinction matters. A good nose tackle can win his assignment. An elite one can force the offense to change its blocking plan before the snap. That adjustment may create favorable matchups elsewhere, even when the ball never travels near him.
Why the best nose tackles still deserve a premium
NFL roster construction often favors obvious production. Edge rushers collect sacks, linebackers pile up tackles, and cornerbacks gain recognition through interceptions. Nose tackles rarely enjoy the same statistical spotlight, even though their assignments can shape everything that happens behind them.
Their value becomes clearer when coaches examine what happens without them.
A defense that loses interior control can start surrendering efficient runs on first down. Offensive coordinators then get comfortable calling play-action, screens and manageable third-down concepts. Those small advantages accumulate, forcing defenders to handle a wider range of possibilities on nearly every snap.
For teams choosing between a specialist and a more versatile interior defender, defensive success rates should inform the decision. A pure run-stuffer who cannot threaten the quarterback may struggle to justify premium snaps against spread formations. Offenses can exploit those limitations by throwing on early downs or accelerating the tempo.
An exceptional nose tackle offers more. He can hold against double teams, disrupt inside zone and demand protection help when the offense drops back. That versatility matters because defensive coordinators no longer want their personnel substitutions to announce the coverage or pressure package.
The strongest argument for paying an elite nose tackle is not simply that he stops rushing yards. He protects the flexibility of the entire front, allowing coaches to defend different offensive looks without constantly changing personnel.
Lawrence’s move to Cincinnati illustrates how highly teams can value that skill set. The Bengals surrendered the No. 10 overall selection in the 2026 NFL Draft to acquire him, betting that his presence could reshape their defensive front.
Such an investment carries risk, especially when an interior defender’s impact can depend heavily on the linebackers and edge rushers around him. But the right nose tackle gives a coordinator something difficult to manufacture through scheme alone: a player who can physically deny the offense its preferred point of attack.
The next great nose tackle might finish with three tackles and win the game
Return to Lambeau Field on that January afternoon in 2021.
Vea had spent months rehabilitating his ankle, working toward a postseason return that once seemed unlikely. Tampa Bay’s reporting on his recovery described how he continued attending team meetings and following the defense while injured. When his chance finally arrived, he stepped back into a championship game against Aaron Rodgers and one of the NFC’s most dangerous offenses.
The box score offered almost nothing in return: 33 defensive snaps, no official defensive statistics and a victory that sent the Buccaneers to the Super Bowl.
Those figures capture the strange economics of playing nose tackle in the NFL. The defender can control an enormous amount of space without claiming much statistical credit for it.
Today, defensive success rates offer a better way to recognize that influence, especially when teams combine them with blocking assignments and individual film study. They also reveal why tackling numbers alone can distort a player’s value. A linebacker may collect eight tackles because his nose tackle repeatedly keeps guards away from him. The front office needs to recognize both contributions before deciding who deserves the next contract.
The 2026 Next Gen Stats models should make those judgments more precise. Coaches can compare what the offense designed with what actually happened, then investigate the defender who forced the change. That could reshape how teams judge interior defensive tackles, rewarding players who protect gaps as well as those who penetrate them.
For Vea, the lesson has been visible for years. He does not need to chase a running back across the field to change a possession. Sometimes, he simply plants himself over the center, refuses to move and makes everyone behind him more dangerous.
The crowd remembers the linebacker who delivers the hit. The scoreboard reflects the drive that ends. Defensive success rates help connect those two outcomes to the massive defender standing in the middle.
And when another offense faces third-and-two, that defender might be the most valuable player nobody notices.

FAQs
Q1. What are defensive success rates in the NFL?
Defensive success rates show how often a defense prevents an offense from gaining enough yards to stay on schedule.
Q2. Why do elite nose tackles sometimes record so few tackles?
Nose tackles often absorb double teams and keep offensive linemen away from linebackers. Their teammates finish the plays they help disrupt.
Q3. How do double teams affect an NFL running game?
When two blockers engage one nose tackle, another defender can attack the running back without fighting through an offensive lineman.
Q4. Why was Vita Vea important to the Buccaneers’ 2020 defense?
Vea controlled the interior and attracted extra blockers. His return helped Tampa Bay pressure Aaron Rodgers during the NFC Championship Game.
Q5. Can defensive success rates measure a nose tackle’s true value?
They help, but they don’t tell the entire story. Coaches also study blocking assignments, double teams and individual performance.
