Boom or Bust? The Circumstances that Propel an NFL QB

There is an innate sense of cohesion and codependence in American football. An ethereal string ties the fates and performances of each player to the rest of their squad, and no matter how good one is, it is inescapable. The 25 highest-scoring offenses of all time have resulted in only 3 championships, with none of the Top 10 winning it. While the greatest defenses have fared better, the results are not extremely pretty either. 

One singular position cannot win (or perform well) without the other, and that is most true for perhaps the single most important position in all of team sports, an NFL Quarterback. It starts up front, even before the ball is in their hands. A porous offensive line makes it nearly impossible for a quarterback to perform well, and a bad defense forces a quarterback to backpack his team with no help from the other side, and the same can be said for every position and their impact on a QB's play. 

This inherent disconnect leads to so much of what we see today, reclamation projects at QB. Sam Darnold with the Vikings (& Seahawks), Baker Mayfield with the Bucs, Geno Smith with the Seahawks, Daniel Jones (maybe) with the Colts, all of these are/were franchise/multi-year starters who had been cast aside by teams with horrific situations surrounding them. 

All of this was propelled by recent Michael Mackelvie videos where he examined who is considered a good quarterback, and why we still don't know who is good at football.

Here's my attempt at quantifying the various factors that influence QB play and their impact on a QB's performance using data from the last 5 years. 



Boom or Bust? The Circumstances that Propel an NFL QB



Statistics Used

Offensive Line (Overall Win Rate): Developed by ESPN, this statistic is broken up into Pass & Run Block Win Rate, which I combined based on weighted averages. The pass block win rate conveys the rate at which offensive linemen are able to hold their block for at least 2.5 seconds, while the run block win rate conveys how effective the line is in the running game by holding off blockers and creating open running lanes. 


Defensive Line (Overall Win Rate): Developed by ESPN, this statistic is broken up into Pass Rush & Run Stop Win Rate, which I combined based on weighted averages. The pass rush win rate conveys the rate at which defensive linemen are able to beat their block in <2.5 seconds, while the run stop win rate conveys how effective they are in stifling the run game and limiting yards.

Pass Catchers (ESPN Receiver Score): Developed by ESPN, these are metrics that use player tracking and Next Gen Stats to quantify a player's ability to get open, their predicted yards after catch, and their ability to catch difficult passes. Scores were combined based on teams and weighted by routes run by each player.

Rushing Ability (EPA/Rush): EPA/Rush tries to quantify the number of expected points added per rush on any given drive, heavily influenced by yardage and downs situations. 

Overall Defense (EPA/Play): EPA/Play tries to quantify the number of expected points a team gives up per play run by the opponent. In this case, you want this number to be negative, as that suggests your team is good defensively. 

(Yes, each and every statistic used has its drawbacks, but there is never going to be a perfect statistic that can isolate every player's exact performance, so let's make do with what we have.)



Analysis

To incorporate each factor and understand its impact, I used Multiple Linear Regression, a statistical method that models the relationship between a single dependent variable and two or more independent variables. It treated QBR/Passer Rating as the dependent variable and all the other factors as independent variables. 

What were the results of my analysis?

MetricQBR ModelRTG ModelInterpretation
R-squared0.2780.226% of variance explained (QBR fits slightly better)
F-statistic (p-value)9.76 (6.57e-08)7.43 (3.83e-06)Both models are overall significant

When you look at how well each model fits, the numbers tell a clear story. The QBR model explains about 28% of the variation in quarterback performance, while the RTG model accounts for roughly 23%. That means both capture some of what drives great QB play, but plenty of the magic still lies beyond the stats. The F-statistics show both models are statistically sound, meaning the predictors as a group genuinely help explain performance. Still, football is wonderfully unpredictable, and while analytics can spot trends, the human side of the game keeps the rest deliciously uncertain.

Receiving_Value0.3290.0070.4110✅ Highly significant
Rushing_Value57.103029.1870.016✅ Highly significant

When you boil it down, the data tells a clear story about what really drives quarterback performance. The model shows that having strong receivers and a productive run game are the biggest difference-makers for both QBR and passer rating. In fact, receiving value and rushing value were the only two variables that showed up as statistically significant, meaning they actually measurably move the needle. Offensive and defensive line win rates, along with overall defensive efficiency, didn’t seem to matter much once the ball was snapped. It’s a reminder that even in a league obsessed with protection and pass rush, quarterbacks still shine the brightest when surrounded by playmakers who can catch and a ground game that keeps defenses honest.

Who would have thought? 
Jalen Hurts has basically been living in quarterback paradise. Sitting at the top across multiple years, Hurts has had it all: an elite O-line that could protect a small village, a pair of star receivers who make every throw look easy, and a running game that keeps defenses guessing. His supporting cast has been a luxury car lineup, and it shows. 

Lamar Jackson, on the other hand, has been carrying Baltimore with less flash out wide but the same steady dominance in the trenches. The Ravens’ ground game and line play have been so strong that Lamar doesn’t even need elite receivers to stay in the mix. Props also go out to Geno Smith for his 2023 bump surrounded by high-end receivers, Jared Goff leading a loaded Lions roster in 2024, Josh Allen posting monster numbers in that heartbreaking “13-second” loss, and Jimmy Garoppolo’s 2022 run when every 49ers weapon was actually healthy at the same time, a once-in-a-lifetime event.

On the other end of the spectrum, we’ve got the quarterback purgatory list; the guys trapped in football’s equivalent of customer service hold music. Gardner Minshew tops it off in 2024 with a Raiders roster that might as well have been crowd-sourced, while Tom Brady’s 2022 finale was a masterclass in boring football and not scoring. The Jets appear again, because of course they do, with quarterbacks who’ve had fewer weapons than a Nerf war and O-lines that crumble faster than cookies. The Patriots, post-Brady, were a full-blown sitcom: multiple coordinators, zero direction, and wideouts that even fantasy owners ignored. Matt Ryan’s Colts era? So forgettable it feels like a fever dream. Davis Mills and Bryce Young had the “we’re rebuilding” excuse, and Tua’s early years were more survival drills than football. And then there’s Trevor Lawrence, who went from MVP candidate to limping through losses after his injury, turning a 1-seed run into a sad 9-8 miss. Rough times all around.

BUF2020Josh Allen12.14
DET2020Matthew Stafford11.95

If you look at this list of quarterback seasons that most outperformed their statistical expectations, you’ll notice it’s packed with the usual suspects. Patrick Mahomes appears twice, which almost feels like a given at this point. Joe Burrow, Josh Allen, Dak Prescott, Justin Herbert, and Green Bay-era Aaron Rodgers are all here, too, each representing stretches when they were at the peak of their powers. Rodgers’ 2020 season stands out in particular; that was vintage MVP-level stuff, the kind of year where everything he threw looked effortless.

Then there’s Lamar Jackson in 2024, who broke football in the best way possible. The Ravens built a perfect setup around him, yet he still shattered every metric. By rating standards, it wasn’t just one of his best seasons; it was one of the best ever. Ryan Fitzpatrick’s 2020 run still feels like a fever dream. Supposed to be a placeholder in Miami, he turned back into “FitzMagic” for a few months, lighting up defenses out of nowhere. And pre-assault Deshaun Watson? That 2020 season was the version Cleveland thought they were trading for: a top-five QB who could carry an offense on his back.

It’s hard not to miss how many names here are from 2020. Clearly, that season was quietly legendary for quarterbacks Rodgers, Mahomes, Allen, Watson, Prescott, and even Fitzpatrick.

PHI2023Jalen Hurts-13.10

It’s a brutal list, the Hall of Shame for modern quarterbacks. Every name here tells a story of what could’ve been and what definitely wasn’t.

Start with Baker Mayfield, Carolina edition. A former No. 1 pick who was once supposed to save Cleveland, flailing so badly that he was told to go home and think about retiring. Will Levis, a year and a half into his career, is already seeing the bench before his rookie contract even cools off. Kenny Pickett, benched in a playoff game while perfectly healthy, was watching from the sideline as his team tried to win without him.

Then there’s rookie Zach Wilson, running for his life behind no protection and throwing to ghosts. Mac Jones, stuck in the Patriots’ chaos with defensive coaches calling offensive plays. Anthony Richardson, whose season last year was so historically bad that it almost redefined what “raw” means. Jalen Hurts, usually superhuman, suddenly looked mortal in that strange 2023 funk. And Trevor Lawrence, the can’t-miss prospect, got Urban Meyer’d into one of the most miserable rookie seasons ever.

Each name on this list isn’t just about bad football; it’s about chaos, mismanagement, and timing gone wrong. It's the who's who of the worst QB seasons over the last few years, and the numbers back it up.

The numbers say plenty, but the stories behind them say more. Josh Allen sits atop both charts, his predicted QBR and rating reflecting a Buffalo offense humming with balance. With one of the league’s better lines, a solid group of receivers, and James Cook thriving in the backfield, Allen looks every bit the engine of a complete attack. Jordan Love isn’t far behind, buoyed by Josh Jacobs and a young, explosive receiving corps, plus a defense that lets him play loose and confident. Daniel Jones has finally been given the supporting cast he’s always needed, led by Jonathan Taylor and a group of playmakers that make every snap dangerous. Dak Prescott remains steady and sharp, feeding two top-tier receivers while leaning on Javonte Williams, one of this season’s most complete runners. Then there’s Bo Nix, quietly sitting among the elite, helped by strong protection, versatile weapons, and a defense that keeps him in control of every game. Even Jayden Daniels, whose season has swung between flashes and frustration, has shown what he can do when his weapons click. The takeaway is simple: talent lifts talent, and the quarterbacks surrounded by the most complete rosters are the ones dominating the predictions.

Justin Fields90.114

The numbers at the bottom tell their own story. Justin Herbert’s drop-off comes despite his arm talent, weighed down by an injury-riddled line that lost Rashawn Slater and missed Joe Alt for stretches, leaving him scrambling behind shaky protection. Cam Ward’s situation might be the league’s toughest, with no real help anywhere; thin receiver depth, a weak line, no run game, and a defense that can’t keep pace. Spencer Rattler’s in a similar spot, forced to do everything himself on a roster short on playmakers. Justin Fields faces many of the same problems, with flashes of brilliance overshadowed by inconsistency around him. Dillon Gabriel might have the defense to keep games close, but with a receiving corps that ranks dead last, he’s fighting uphill every week. These quarterbacks aren’t short on talent, but the support around them has turned every throw into a test of survival.

This year’s overperformers list is led by a breakout that’s impossible to ignore. Drake Maye has taken the leap from promising rookie to full-fledged franchise quarterback, leading the Patriots to the top of the AFC East and playing with the poise of a veteran. His precision and command have transformed an offense once desperate for rhythm. Right behind him is Sam Darnold, whose resurgence in Minnesota last season wasn’t a fluke; it’s carried right into Seattle, where he’s thriving in a system built around his strengths. The rest of the list reads like a roll call of the league’s elite. Jalen Hurts, Jared Goff, Dak Prescott, Matthew Stafford, Justin Herbert, and Patrick Mahomes are all doing what stars do: finding ways to elevate their teams even when expectations are already sky-high.

Trevor Lawrence-13.216

It’s a rough list, and it tells you a lot about how the season has unfolded. Russell Wilson, Jake Browning, and Geno Smith have all seen the bench, each struggling to match even modest expectations in offenses that fell apart early. For Wilson, it’s been a steady decline; for Browning and Smith, flashes of competence couldn’t outweigh inconsistency. Cam Ward and Dillon Gabriel, both rookies, have had it even tougher, failing to rise above already bleak situations and looking overwhelmed against NFL speed and pressure. The surprise name is Trevor Lawrence, a player too talented to be here, but the Jaguars’ endless drops and stalled drives have dragged down his numbers and confidence alike. 


Conclusion

If there’s one thing this all proves, it’s that quarterback play is beautifully unpredictable. The data may outline the scaffolding of success, but the actual performance lives in the space between numbers, in confidence, rhythm, trust, and timing. A quarterback’s greatness depends as much on the five linemen in front of him and the chemistry with his receivers as it does on arm strength or football IQ. Football isn’t just interconnected; it’s symbiotic. Every block, every cut, every read shapes what happens next. And that’s what makes it so fascinating, no stat can ever fully capture the chaos and cohesion that define this sport. So, what do you think? Which of these results surprised you the most, or whose the one player you didn’t expect to see here?
