Buffalo Bills | News, Scores, Schedules & Standings

The Buffalo Bills have welcomed plenty of new pieces into the fold this offseason, particularly on the defensive side of the ball.

As part of an overhaul led by new defensive coordinator Jim Leonhard, the Bills remade their edge rusher room, signed two safeties with starting experience and drafted potential starters at cornerback and linebacker.

While multiple core pieces return, everyone must establish themselves in a new system in front of new coaches. That task is especially important for any newcomers who have aspirations to start.

Sports Illustrated senior reporter Albert Breer mentioned four defensive newcomers who will be tested during training camp.

"Speaking of new coaches, the Bills’s shift in philosophy comes on the head-coaching side, since new boss Joe Brady was promoted from the offensive coordinator spot. So veteran additions such as Bradley Chubb, C.J. Gardner-Johnson and Geno Stone, and draft picks like DE T.J. Parker are headed into a critical summer," said Breer.

Conversely, Breer suggested that wide receiver DJ Moore's familiarity with head coach Joe Brady will make matters less challenging for him this summer.

As for what's at stake and how they will fare, here's are some thoughts on the four potential defensive starters.

OLB Bradley Chubb

Chubb is changing teams, but he's joining a familiar scheme that could potentially bring out the best in him.

"He's played in very similar defenses the majority of his career, even at Miami, so excited to have him for the player that he is - the experience, the versatility he has, and the leadership," said Leonhard.

In a positive development for the Bills, the former No. 5 overall draft pick has already started establishing himself as a leader. In that spirit, Chubb invited Parker to train with him in South Florida during the current break.

Although Chubb, whose 8.5 sacks were enough to lead the Bills in 2025, is the presumed starter opposite Greg Rousseau, he must work to leave no doubt this summer. Buffalo needs him to become the closer that the pass rush has lacked for years.

S Chauncey Gardner-Johnson

Gardner-Johnson's explosive personality has resulted in the talented defensive back playing for four different teams in the past three seasons. Although it's still early, the fiery safety has seemingly struck all the right chords thus far.

"We're excited about just his passion and energy for the game and what he brings into the building every day," said Leonhard.

We wrote about the Super Bowl LIX champion making his presence felt during June minicamp when he managed to pick off a pass from Josh Allen.

"He's a competitor. He's the loudest guy in the room at all times. He's a constant competitor, and nothing that he does is half speed. He does it full speed," said Allen.

Gardner-Johnson, who notched two six-interception seasons for the Philadelphia Eagles (2022, 2024), is the favorite to start at safety alongside 2024 second-round pick Cole Bishop.

S Geno Stone

Stone has seemingly flown under the radar a bit since signing with the Bills in mid-March. The 27-year-old, who has not missed a game in the last four seasons, figures to compete against the Gardner-Johnson for a starting role.
