The Buffalo Bills kicked off their 2026 training camp on July 29 at St. John Fisher University in Pittsford, New York, marking the start of a new era under head coach Joe Brady.
The camp will later move to the new Highmark Stadium in Orchard Park, New York.
Defensive Overhaul Under Jim Leonhard
Defensive coordinator Jim Leonhard has shifted the Bills from a 4-3 to a 3-4 base scheme, aiming for a more aggressive and flexible style.
Leonhard, who played in 3-4 defenses during his NFL career, acknowledged the unit's evolution.
"I have a vision for what I want it to be, and it might not totally get there in year one," he said.
He added, "We're going to be an attacking defense up front and on the back end."
Leonhard plans to use various packages and leverage player versatility.
"We're going to get to a lot of different packages where we can put different people in there playing slot and not solely put it on one person," he explained.
The defensive line will be key, with Michael Hoecht and Ed Oliver returning to boost the pass rush.
Free agent addition Bradley Chubb and rookie TJ Parker add depth.
Chubb stated, "Getting after the quarterback is what we're going to be about. I feel like I'm one of those pieces to help us get over the hump."
The defense aims to set the tone aggressively rather than reacting to offenses.
On offense, quarterback Josh Allen faces pressure to lead through changes.
Tight end Dalton Kincaid aims to stay healthy after injury setbacks, while linebacker Terrel Bernard looks to rebound in the new system following a difficult 2025 season.
Position battles include left guard between veteran Austin Corbett and Alec Anderson, and punter between rookie Tommy Doman Jr. and Mitch Wishnowsky.
The wide receiver room is under evaluation, with questions about Tyrell Shavers' health and potential contributions from Keon Coleman and rookie Skyler Bell.
Fans can engage at the One Bills Live event at Pittsford Wegmans on July 27, where memorabilia from the old stadium will be available.
The Bills also introduced new parking and tailgating rules at the new stadium, including bans on megaphones and air horns and limits on music volume.
The secondary has seen notable changes, with new additions at cornerback and safety to replace departing veterans.
Depth and versatility in the defensive backfield will be critical for Leonhard's evolving strategy.
