Bold claim: The Cowboys’ 2026 defense needs a seismic shift, and nine coaching options stand out as potential game-changers if Dallas decides to pivot. After their Sunday night loss to the Vikings, Dallas sits on the fringe of the playoffs, and Dak Prescott himself acknowledged the grim reality. With that, the loudest finger-pointing has pointed at defensive coordinator Matt Eberflus, and Jerry Jones has signaled the possibility of a coordinator overhaul once the season ends.
Why this matters: Eberflus has a track record of strong defenses elsewhere, but Dallas hasn’t seen that same level of impact. A brief uptick after the trade deadline gave fans a spark, yet the defense quickly regressed, and Dallas now ranks among the league’s less effective units. If the Cowboys choose to make a change, here are nine coaches who could plausibly bolster the defense in 2026, presented with context, fit, and potential pathways to Dallas.
Jim Schwartz
Leading the list is Jim Schwartz, who’s currently destabilizing quarterbacks’ Sundays as the Browns’ defensive coordinator. Luring him to Dallas would require maneuvering around organizational realities in Cleveland, where the team is mired in a disappointing season and head coach Kevin Stefanski’s job security is under scrutiny. If Stefanski is dismissed, Schwartz becomes a prime target; even in a scenario where Stefanski stays, Schwartz could pursue a more stable opportunity elsewhere. Dallas would welcome him, especially given Brian Schottenheimer’s growing credibility within the organization.
Schwartz’s approach aligns well with the Cowboys’ roster. His background under Jeff Fisher and Gregg Williams emphasizes physicality and aggressive play. He favors press-man coverage and, while not aggressively blitz-happy, often uses simulated pressures to pressure offenses with four rushers. Landing Schwartz would feel like a near-perfect match for Dallas’ defensive DNA.
Jim Leonhard
Jim Leonhard has emerged as a rising star in coaching circles. The Broncos’ defense, under Vance Joseph, has been one of the NFL’s better units, with Denver ranking top contenders in EPA per play allowed. Leonhard, currently the Broncos’ assistant head coach and pass game coordinator on defense, could be the target if the Cowboys want to modernize their defense without a complete rebuild. His résumé includes a productive stint as Wisconsin’s defensive coordinator, where his units thrived, and even a brief period as interim head coach at Wisconsin, showcasing leadership potential.
Leonhard’s strengths include modernizing defenses and pairing well with innovative offensive coordinators. He has a connection to Dallas via former Jets offensive coordinator (Schottenheimer) and his own NFL playing history with the Jets. The upside is a fresh, modern scheme that could elevate Dallas’s defense quickly; the downside is the risk that a coach’s success in Denver or Wisconsin doesn’t translate to Dallas’s unique culture or personnel. Still, his rise suggests a head-coaching trajectory, which means Dallas could attract him now or in the near future.
Mike Pettine
Mike Pettine, currently the Vikings’ assistant head coach and outside linebackers coach, presents another familiar face with strong ties to Schottenheimer. Pettine’s lineage traces back to Rex Ryan and a long run as a defensive coordinator, including a notable stint with the Jets. His connection to Schottenheimer, plus his experience in multiple organizational cultures, could help him adapt quickly to Dallas.
Pettine’s defensive philosophy leverages a versatile mix of schemes and a focus on fundamentals, with a history of turning around run defense and coordinating pass rush schemes. The challenge would be reconciling his presence with the current staff and ensuring his system fits the Cowboys’ personnel and long-term plan. Still, his background suggests he could deliver results with the right players and leadership around him.
Ken Norton Jr.
Jerry Jones has a history of revisiting familiar voices, and Ken Norton Jr. fits that impulse. Norton currently coaches linebackers for Washington, but his résumé includes seven years as a defensive coordinator with the Raiders and Seahawks, and multiple years coaching linebackers under Pete Carroll. He has deep connections to Dan Quinn, Jeff Schottenheimer, and the broader Dallas ecosystem. Norton is Cowboys royalty, a former second-round pick who won three Super Bowls with Dallas and earned three Pro Bowl selections.
Norton would bring veteran savvy and a recognizable allocation of style and language from the Cowboys’ recent successes. He wouldn’t be the flashiest hire, but his experience, leadership, and strong ties to the franchise could translate into meaningful improvements, especially in the linebacking corps and overall defensive coherence.
Leslie Frazier
Leslie Frazier has long been associated with solid defensive performance. His recent work as Seahawks assistant head coach has kept him close to high-level defensive thinking under Mike MacDonald. Previously, Frazier ran the Bills’ defense for six seasons, contributing to some of the franchise’s most successful defensive years. His breadth of experience across winning programs makes him an attractive, steady option.
Frazier isn’t the loud headline pick, but his track record is proven. His familiarity with successful, modern defenses and his proximity to winning programs in recent years could make him an effective internal stabilizer who could rapidly implement a strong scheme in Dallas.
Patrick Graham
If the Cowboys want a Flores-like influence but prefer a different path, Patrick Graham from the Raiders is a compelling option. Graham has survived multiple coaching changes in Las Vegas, maintaining a functional defensive system that performed respectably in recent seasons (13th in EPA/play, and 7th in EPA/rush allowed). Rumors of friction with the Raiders’ new head coach suggest a potential exit, which could open the door for Dallas.
Graham’s scheme shares a Bill Belichick–origin philosophy with Flores, favoring fluid, adaptable concepts that emphasize defense in a flexible, attacking posture. If Dallas wants a coach who can implement a modern, aggressive yet adaptable scheme, Graham presents a strong case, particularly for teams seeking to replicate Flores’ success without copying him verbatim.
Cory Undlin
Cory Undlin has built a notable résumé as a defensive coach with a knack for coaching defensive backs and coordinating pass defenses. He’s worked with DeMeco Ryans in Houston and San Francisco, including a stint as the 49ers’ pass game specialist and secondary coach, and he’s earned a reputation for helping develop young playmakers like Derek Stingley and Jalen Pitre in Houston.
Undlin’s breadth includes prior success coaching the Broncos’ defensive backs during the Peyton Manning era and contributing to a Super Bowl-winning Eagles secondary under Jim Schwartz. His background as a developer of talent and his experience across multiple schemes could give Dallas a versatile, modern look that adapts to personnel and game plans.
Aubrey Pleasant
Aubrey Pleasant’s career trajectory has been rapid, with prominent stops in Cleveland, Washington, and Los Angeles. He gained traction with Mike Pettine’s Browns staff and later with Sean McVay’s Rams, where he coached cornerbacks. Pleasant then moved to Detroit as the defensive backs coach and pass game coordinator, where the defense faced ups and downs before a mid-season departure during a challenging campaign. He returned to the Rams, where he’s spent the past few seasons as the cornerbacks coach and passing game coordinator.
Pleasant has demonstrated talent development and a knack for scheming effective pass defense, even amid personnel upheavals in Los Angeles. His ability to cultivate talent and adapt schemes under pressure could bring a fresh, modern edge to Dallas’s back end.
Paul Guenther
Returning to a familiar player-scheme dynamic, Paul Guenther could be a pragmatic reset for Dallas. The Cowboys showed progress late last season under Mike Zimmer’s defensive framework, and Guenther, Zimmer’s longtime lieutenant, would bring that same philosophy back to the forefront. He previously served as the team’s defensive run game coordinator before shifting roles following the Eberflus hire.
Guenther’s strength lies in blitz timing, press man principles, and a disciplined approach to run defense—elements that previously meshed well with Dallas’ personnel. His recent stint with UNLV as interim defensive coordinator demonstrated his ongoing coaching acumen and willingness to adapt, even in a college setting. If Dallas wants to re-embrace the Zimmer-era style with modern touches, Guenther is a thoughtful, potentially high-reward option.
If Dallas were to pivot toward a new era on defense, any of these coaches could reshape the club’s unit in meaningful ways. Each candidate brings a distinct blend of philosophy, familiarity with Dallas culture, and a track record of improving defenses in different environments. The challenge lies in identifying the right fit for the current roster, the ownership's long-term vision, and the organizational stability required to sustain success.
What do you think would be the most impactful short-term move for the Cowboys’ defense in 2026? Do you favor a veteran, proven coordinator with a recognizable style, or a rising innovator who could grow with the roster over time? Share your thoughts in the comments.
