Buffalo, NY – The winds of change are howling through Orchard Park, and Bills fans, buckle up: it’s about to get even more exciting! With the Sean McDermott era firmly in the rearview mirror, new head coach Joe Brady is wasting no time reshaping the Buffalo Bills into a championship contender. His boldest stroke yet? Bringing in Jim Leonhard as the team’s defensive coordinator – and now, whispers from the league suggest Leonhard is poised to orchestrate a blockbuster reunion by luring a key Denver Broncos standout to Western New York. Enter Alex Singleton, the Broncos’ defensive commander and a pending free agent who’s tailor-made to ignite the Bills’ defensive turnaround.

For years, the Bills’ defense has been the Achilles’ heel of an otherwise explosive team. Despite Josh Allen’s heroics at quarterback, defensive lapses have derailed playoff runs time and again. Last season’s heartbreaking loss to the Denver Broncos in the playoffs? Sure, Allen’s four turnovers didn’t help, but the unit’s inability to stop the run and generate consistent pressure has been a recurring nightmare. Enter Joe Brady, the offensive mastermind who stepped up from interim duties to full-time head coach, signaling a fresh start. One of his first major decisions was poaching Jim Leonhard from the Broncos, where he served as pass-game coordinator under a defense that dominated the NFL landscape.

Leonhard’s credentials are impeccable. Over the last two seasons, Denver’s defense has been a juggernaut – arguably the league’s best – suffocating offenses with elite secondary play and a relentless front seven. Leonhard had a front-row seat to greatness, working alongside stars like Pat Surtain II, the consensus top corner in the game. His expertise in scheming against the pass while maintaining a stout run defense made him the perfect fit for Buffalo’s needs. “If Leonhard can replicate even half of Denver’s success here, we’re talking Super Bowl potential,” one league insider told us. But to truly transform this unit, Leonhard knows he needs familiar pieces – and that’s where Alex Singleton comes in.

Singleton, a 32-year-old linebacker who’s been the heart and soul of Denver’s defense for the past four seasons, is set to hit free agency this offseason. Don’t let the “under-the-radar” label fool you – this guy is a tackling machine. In five of his seven NFL seasons, Singleton has racked up 100+ total tackles, showcasing an uncanny knack for sniffing out plays and batting down passes at the line. His eye for the ball and leadership qualities have made him a defensive commander on the field, barking orders and rallying the troops in high-stakes moments.

As highlighted by CBS Sports’ Zachary Pereles in his list of underrated free agents, Singleton’s run-stopping prowess is elite. “PFF graded him very highly as a run defender and not as highly as a pass defender. Still, he can provide solid play in the middle, especially when behind an impactful defensive line,” Pereles noted. This couldn’t be more relevant for the Bills, who struggled mightily against the run in 2025, allowing opponents to gash them for chunk yards and control the clock. Buffalo’s defense ranked near the bottom in run defense efficiency last season, a glaring weakness that cost them dearly in the playoffs.

What makes this potential move a no-brainer? Familiarity breeds success. Singleton has thrived in the defensive scheme Leonhard helped craft in Denver, making the transition seamless. Imagine Singleton anchoring the middle, stuffing runs and freeing up edge rushers like Von Miller (if re-signed) or emerging talents to hunt quarterbacks. The Bills prioritize versatility, but as Pereles points out, not every player needs to be a Swiss Army knife. Sometimes, you need a specialist who excels in one area – and Singleton’s run defense is that hammer the Bills desperately need.

Financially, this is a steal. According to Spotrac, Singleton’s projected market value sits at a modest $4.7 million annually – pocket change for a Bills team with ample cap space heading into 2026. It’s a win-win: Buffalo gets a proven leader and run-stopper at a discount, while Singleton reunites with Leonhard on another AFC powerhouse, chasing rings in a high-powered offense led by Allen.

Of course, growing pains are inevitable. Leonhard will need to get creative, cleaning up the messes left from the previous regime and integrating new faces. But landing Singleton could be the catalyst that propels this defense from liability to lockdown unit. If this blockbuster happens – and sources say talks are heating up – it won’t be long before Leonhard’s name is back in head-coaching conversations.

Bills Mafia, the pieces are falling into place. Jim Leonhard isn’t just building a defense; he’s engineering a revolution. Stay tuned – this familiar face might just lure the Broncos’ commander to Buffalo and turn the tide for good. Go Bills!
