The Buffalo Bills enter the 2026 season with one of the NFL’s most talented rosters, but questions remain about whether every position group is built for a championship run. Among the concerns surrounding the team, linebacker has emerged as the area drawing the most attention heading into training camp.
Despite returning a defense filled with experienced contributors, the Bills face uncertainty at the second level. The linebacker unit lacks the same proven depth found at several other positions, creating questions about how the defense will respond if injuries occur or if younger players fail to develop into consistent contributors. That uncertainty has placed added importance on competition throughout the offseason.

Buffalo has built its recent success on disciplined defensive play and an aggressive scheme capable of limiting explosive offenses. The front four has consistently generated pressure, while the secondary features playmakers capable of creating turnovers. However, the linebacker position remains responsible for connecting every level of the defense, making it one of the most demanding roles on the field.
The challenge extends beyond stopping the run. Modern linebackers must also cover athletic tight ends, defend running backs in space and communicate adjustments before the snap. Any inconsistency at the position can create favorable matchups for opposing offenses, particularly against teams that rely on versatile playmakers in the passing game.
ESPN’s NFL Expert Highlights Buffalo Bills’ Biggest Weakness Before 2026 Season

A league expert shared his thoughts about Buffalo’s mayor weakness ahead of the new NFL season. This is detailed more in an analysis by Mike Clay for ESPN.
Biggest weakness: Off-ball linebacker. Terrel Bernard remains the team’s top LB, but he has battled injuries (nine total games missed) and ineffectiveness in each of the past two seasons. Running mate Dorian Williams has generally been a situational player but might need to play an expanded role this season. Demetrius Flannigan-Fowles and fourth-round rookie Kaleb Elarms-Orr are his primary competitors. Buffalo might lean a bit more on three-safety looks in the post-Sean McDermott era due to its LB situation.
The Bills still have reasons for optimism as training camp approaches. Younger linebackers will have opportunities to earn larger roles, while the coaching staff has repeatedly demonstrated an ability to develop defensive talent. If one or more emerging players establish themselves alongside the veteran leaders already on the roster, Buffalo could quickly transform a perceived weakness into a dependable position group.
Expectations remain high because the Bills possess enough talent to compete with any team in the league. Whether they can take the final step toward a championship may depend on how effectively the linebacker unit performs throughout the season, making it one of the most closely watched position battles as Buffalo begins another pursuit of a Super Bowl title.
