🟦 Sean McDermott’s Legacy in Buffalo: A Decade That Rewrote the Franchise Record Book
​

When the Buffalo Bills hired Sean McDermott on January 11, 2017, they weren’t just looking for a coach — they were looking for a reset. Seventeen years without a playoff appearance. A revolving door of coaches and quarterbacks. A fanbase that had endured more heartbreak than any in the league. McDermott walked into that storm with a wrestling‑champ mentality and a blueprint built on discipline, culture, and consistency.
​
Nine seasons later, the Bills fired McDermott this morning after a divisional‑round loss in Denver. But the story of his tenure isn’t defined by the ending. It’s defined by the transformation he engineered — one of the most dramatic in modern NFL history.
​
This article is a look at Sean McDermott’s top 10 accomplishments in Buffalo, backed by the numbers and league records that shaped his legacy.
​
1. Snapping the 17‑Year Playoff Drought (2017)
​
McDermott’s very first season delivered what Bills fans had been begging for since 1999: a postseason berth. He became only the third coach in franchise history to reach the playoffs in Year 1.
​
2. Seven Playoff Appearances in Nine Seasons
​
From 2017–25, Buffalo reached the postseason seven times, a level of consistency the franchise had never experienced in the Super Bowl era.
​
3. Five Straight AFC East Titles (2020–24)
​
Before McDermott, the Bills had never won five consecutive division titles. Under him, they dominated the AFC East from 2020–24, ending New England’s two‑decade reign and establishing Buffalo as the new standard in the division.
​
4. One of the Best 8‑Year Starts in NFL History
​
McDermott’s 86 regular‑season wins from 2017–24 rank second all‑time for any coach in their first eight seasons, trailing only George Seifert’s 98.
​
5. The Winningest Coach in Bills History by Win Percentage
​
His .662 regular‑season winning percentage (98–50) is the best in franchise history, and his 98 wins trail only Hall of Famer Marv Levy’s 123.
​
6. Ending a 25‑Year Playoff Win Drought (2020)
​
Buffalo’s 2020 postseason run delivered the franchise’s first playoff victory since 1995, culminating in an AFC Championship appearance.
​
7. Sustained 10‑Win Excellence Matched Only by Kansas City
​
From 2019–24, the Bills and Chiefs were the only two teams in the NFL to win 10+ games and make the playoffs every single year — a testament to Buffalo’s stability and McDermott’s program.
​
8. National Recognition: Coach of the Year Honors
​
McDermott earned multiple nods for NFL Coach of the Year, including finishing 2nd in 2020 and winning the Maxwell Club’s Greasy Neale Award in 2024.
​
9. Two AFC Championship Game Appearances
​
The Bills reached the conference title game in 2020 and 2024, falling both times to Kansas City but reestablishing themselves as a legitimate Super Bowl contender.
​
10. A Cultural Overhaul That Changed the Franchise’s Trajectory
​
League observers consistently credit McDermott with reshaping Buffalo’s identity — from a team defined by droughts and dysfunction to one known for discipline, competitiveness, and year‑over‑year stability.
​
🟦 The Full Picture: A Tenure of Highs, Near‑Misses, and Lasting Impact
​
McDermott’s firing this morning — following a 12–5 campaign and yet another playoff win — reflects the brutal reality of coaching in the Josh Allen era. Expectations weren’t just high; they were Super Bowl‑or‑bust. His 8–8 postseason record and repeated losses to Kansas City ultimately overshadowed the historic progress he delivered.
​
But history won’t forget what he built:
​
-
He took over a franchise stuck in neutral and turned it into a perennial contender.
-
He delivered stability in a league built on chaos.
-
He helped develop Josh Allen from a raw prospect into an MVP‑caliber quarterback.
-
And he restored Buffalo’s place on the NFL map.
For a franchise that had wandered the wilderness for nearly two decades, that transformation alone is monumental.
Did McDermott Deserve To Be Fired?
Sean McDermott’s firing is one of those decisions that can be argued convincingly from both sides, which is exactly why it’s become such a flashpoint in Buffalo and on social media. On one hand, he delivered the most successful sustained run the franchise has seen since the early 1990s — seven playoff appearances in nine years, five straight AFC East titles, two AFC Championship Game berths, and the second‑most wins of any coach in his first eight seasons in NFL history. That résumé doesn’t usually get a coach fired. But the counterargument is equally real: with Josh Allen in his prime, the Bills repeatedly stalled in the same spot, losing to Kansas City in the postseason four times and finishing 8–8 in the playoffs overall. Add in several high‑profile game‑management failures and the sense that Buffalo’s Super Bowl window was being wasted, and ownership clearly felt the ceiling had been reached. Whether he deserved to be fired depends on what you value more — the historic stability he built, or the championships he couldn’t deliver — but it’s undeniable that his tenure raised expectations to a point where anything short of a Lombardi Trophy felt like falling short.
It was reported today that McDermott told his staff that he wants to keep coaching. This guarantees he will be one of the hottest names on the market, and he will not sit unemployed for long. Around the National Football League, owners value stability, culture‑building, and the ability to develop a franchise quarterback, and McDermott checks every one of those boxes. Even with the playoff frustrations in Buffalo, he’s widely respected for turning a long‑dormant franchise into a perennial contender, and teams with defensive talent or young rosters in need of structure will see him as an immediate upgrade. Coaches with his track record almost always get snapped up quickly.
🟦 Top 4 Best‑Fit Coaching Destinations for Sean McDermott
-
Baltimore Ravens — The Most Seamless Cultural Match
Baltimore is the closest thing the NFL has to Buffalo’s organizational DNA: stable ownership, a defense‑first identity, and a roster built around toughness and discipline. McDermott’s program‑building approach fits perfectly with a franchise that values structure and continuity. With Lamar Jackson in his prime and a playoff‑ready roster, this is the cleanest plug‑and‑play opportunity.
​
2. Las Vegas Raiders — A Franchise Desperate for Stability
The Raiders have cycled through coaches and philosophies for two decades, and McDermott’s track record of turning chaos into consistency would be a major selling point. Their defense has cornerstone talent (Maxx Crosby, Nate Hobbs), and ownership has shown interest in experienced, culture‑driven leaders. McDermott would immediately raise the floor.
3. Miami Dolphins — A Rebuild Needing Identity
Miami has talent but lacks the defensive backbone and week‑to‑week consistency that defined Buffalo under McDermott. If the Dolphins move on from their current direction, they’ll need someone who can reset the culture and build a sustainable identity. The fit is strong, though the divisional familiarity cuts both ways.
4. Arizona Cardinals — A Long‑Term Project With Upside
Arizona offers a young roster, draft capital, and a quarterback who needs a defensive‑minded coach capable of building a complete program. McDermott’s strengths align with what the Cardinals lack: discipline, defensive structure, and a long‑term plan. It’s the least “win‑now” destination, but the long runway could appeal to him.
Sean McDermott’s tenure in Buffalo may have ended without the Super Bowl breakthrough fans dreamed of, but it undeniably reshaped the franchise’s identity and expectations. Wherever he lands next, the team that hires him won’t just be getting a coach — they’ll be getting a proven builder who knows how to turn a struggling organization into a contender.
