Cowboys Target Defensive Coaches Who Gave Dak Prescott Trouble in 2025 Season

The Dallas Cowboys’ search for a new defensive coordinator is officially underway, and early signs suggest the team has a very specific profile in mind. Rather than casting a wide net with abstract criteria, Dallas appears to be focusing on defensive coaches who have already proven one thing beyond doubt: they know how to slow down Dak Prescott and the Cowboys’ offense.

This offseason, the Cowboys have taken a noticeably aggressive approach to their coaching search. Interviews began quickly after the season ended, signaling a sense of urgency within the organization. So far, the team has completed interviews with six defensive coaching candidates, with three additional interviews scheduled, bringing the total to nine. The list is deep, diverse, and full of coaches on the rise across the NFL.

Defensive Coordinator Candidates Interviewed by the Cowboys

The Cowboys have already completed interviews with the following candidates:

• Jim Leonhard, Defensive Pass Game Coordinator, Denver Broncos

• Daronte Jones, Defensive Pass Game Coordinator, Minnesota Vikings

• Jonathan Gannon, Head Coach, Arizona Cardinals

• Zach Orr, Defensive Coordinator, Baltimore Ravens

• Ephraim Banda, Safeties Coach, Cleveland Browns

• Aaron Whitecotten, Defensive Line Coach, Dallas Cowboys

In addition, Dallas has interviews scheduled with three more candidates:

• Charlie Bullen, Interim Defensive Coordinator, New York Giants

• Demarcus Covington, Defensive Line Coach / Run Game Coordinator, Green Bay Packers

• Christian Parker, Defensive Backs Coach / Pass Game Coordinator, Philadelphia Eagles

At first glance, this appears to be a standard list of respected defensive minds. However, a closer look reveals a fascinating trend: six of the nine candidates coached defenses that faced the Cowboys this season — and most of them caused serious problems for Prescott and the Dallas offense.

A Pattern Emerges: Defenses That Shut Down Dak Prescott

While defensive success is always a team effort influenced by roster talent and overall coaching philosophy, the results against Dallas this season are difficult to ignore. Several of these candidates were key contributors to game plans that produced some of Prescott’s worst statistical performances of the year.

Games Without a Prescott Touchdown Pass

Prescott had four games this season where he failed to throw a touchdown, and the Cowboys lost all four:

• Week 1 vs. Eagles (Christian Parker)

• Week 8 vs. Broncos (Jim Leonhard)

• Week 15 vs. Vikings (Daronte Jones)

• Week 18 vs. Giants (Charlie Bullen)

Notably, each of those games featured a defensive coach who is now on Dallas’ interview list.

Lowest Completion Percentage Games

Four of Prescott’s five worst completion-percentage games came against teams coached by these same candidates:

• Week 15 vs. Vikings (Daronte Jones): 60.5%

• Week 8 vs. Broncos (Jim Leonhard): 61.3%

• Week 9 vs. Cardinals (Jonathan Gannon): 61.5%

• Week 1 vs. Eagles (Christian Parker): 61.8%

Lowest Passing Yard Totals

Prescott’s three worst passing-yard performances of the season were:

• Week 18 vs. Giants (Charlie Bullen): 70 yards

• Week 8 vs. Broncos (Jim Leonhard): 188 yards

• Week 1 vs. Eagles (Christian Parker): 188 yards

While Prescott only played the first half of the season finale against the Giants, the performance was still concerning. He was on pace for his lowest yardage output of the entire season.

Lowest Quarterback Ratings

Prescott’s three worst QB ratings of the year also came against this group:

• Week 8 vs. Broncos (Jim Leonhard): 51.5

• Week 1 vs. Eagles (Christian Parker): 76.6

• Week 9 vs. Cardinals (Jonathan Gannon): 77.9

The pattern is clear: the Cowboys are interviewing defensive coaches who consistently found ways to disrupt their own offense.

Jim Leonhard: The Name That Keeps Appearing

If Cowboys fans weren’t already familiar with Jim Leonhard, they likely are now. The Broncos appear in every major negative statistical category for Prescott this season. That Week 8 game was one of the most frustrating offensive performances Dallas endured all year.

The Cowboys fell into a 27–10 halftime deficit, a hole they never escaped. Even after Denver turned the ball over on the opening drive, Dallas stalled at the two-yard line. The offense struggled with protection, timing, and rhythm all afternoon. Prescott looked uncomfortable, hesitant, and out of sync — exactly what a defensive coordinator aims to achieve.

Leonhard’s defensive game plan clearly worked, and it’s no surprise he’s at the top of Dallas’ list.

Christian Parker’s Transformation of the Eagles’ Defense

Another standout candidate is Christian Parker, whose impact on the Eagles’ defense cannot be overstated. Before Parker became Philadelphia’s pass game coordinator, Prescott dominated the Eagles. In the three seasons prior, Prescott threw 16 touchdowns and just one interception against Philly, with Dallas scoring 40 or more points three times.

Since Parker’s arrival, that narrative has changed dramatically.

While Dallas split the series with the Eagles this season, neither matchup featured the explosive offense fans had come to expect. Even in Dallas’ comeback win at AT&T Stadium, the Cowboys were aided by Eagles turnovers, poor second-half offense, and a critical special teams fumble that gave Dallas a short field.

The defensive improvement under Parker has been undeniable.

Even Struggling Teams Found Answers

Perhaps most alarming for Dallas is that even struggling teams managed to shut them down. The Minnesota Vikings entered their matchup after losing four straight games, yet Daronte Jones and Brian Flores engineered a defensive performance that completely stifled the Cowboys.

Prescott threw zero touchdowns, and the Vikings’ coverage was so effective that questions began to emerge about Dallas’ receiving corps. That loss proved to be a pivotal moment and essentially marked the beginning of the end for the Cowboys’ season.

The Arizona Cardinals provide an even starker example. They lost 14 of their final 15 games, with their lone win during that stretch coming against Dallas. Head coach Jonathan Gannon, who also called the defensive plays, held the Cowboys to just 10 points, their lowest offensive output of the year.

What This Means for Dallas’ Coaching Search

As the Cowboys move closer to hiring their next defensive coordinator, one thing is clear: they have a type. Defensive coaches who made life difficult for Prescott and offensive coordinator Brian Schottenheimer appear to be at the top of the list.

Whether this approach leads to long-term success remains to be seen. But Dallas is clearly prioritizing firsthand experience, innovation, and proven results against elite talent — even when that talent happens to be their own quarterback.

If a defensive coach embarrassed the Cowboys this season, Jerry Jones and company haven’t forgotten. And that memory may very well determine who runs the Cowboys’ defense in 2026.
