2026 Dallas Cowboys 7-Round Mock Draft: Rebuilding the NFL’s Worst Defense from the Trenches Out

The Dallas Cowboys enter the 2026 offseason facing a harsh but unavoidable reality: their defense has fallen to the bottom of the NFL. Once a unit capable of creating turnovers and game-changing plays, the Cowboys’ defense has deteriorated into the league’s most unreliable group, forcing the front office to rethink its long-term roster-building strategy.

As a result, league insiders widely expect Dallas to use the majority of its 2026 NFL Draft capital on defense, prioritizing foundational talent over short-term fixes. The key question, however, is not whether the Cowboys will invest heavily on defense — but how they should do it.

Should Dallas rebuild by addressing the pass rush first and then repairing the secondary? Or should the team focus on the linebacker corps, which could lose Kenneth Murray, Jack Sanborn, and Logan Wilson in free agency? Each approach carries risk, and the Cowboys must strike the right balance if they want to return to playoff contention.

In this 2026 mock draft scenario, Dallas commits to rebuilding from the trenches outward — starting with the defensive line, reinforcing the secondary early, and trusting young linebackers DeMarvion Overshown, Marist Liufau, and Shemar James to take the next step. With that philosophy in mind, here is a complete seven-round 2026 mock draft for the Dallas Cowboys.

2026 Dallas Cowboys 7-Round Mock Draft

Round 1, Pick No. 12: David Bailey, EDGE, Texas Tech

With the 12th overall pick, the Cowboys have flexibility — and in this mock draft, that flexibility works in their favor.

Elite defensive prospects Arvell Reese, Sonny Styles, Caleb Downs, and Jeremiyah Love all come off the board inside the top 10, allowing David Bailey to slide further than expected. Dallas capitalizes immediately.

Bailey may not be the most explosive or bend-heavy pass rusher in the class, but he is one of the most productive and consistent defenders available. During the 2025 season, Bailey recorded 19.5 tackles for loss in 14 games, continuing a four-year stretch of elite production at Texas Tech.

What makes Bailey especially appealing for Dallas is his versatility. He can win with power, set a strong edge in the run game, and generate pressure without needing to be schemed free. Pairing Bailey with Donovan Ezeiruaku and the Cowboys’ existing interior defenders would give Dallas a defensive line capable of controlling games — something the team has lacked in recent seasons.

This pick represents a philosophical reset: pressure first, coverage second.

Round 1, Pick No. 20: Mansoor Delane, CB, LSU

The Cowboys double down on defense by selecting Mansoor Delane, one of the most technically refined cornerbacks in the 2026 class.

Delane is widely viewed as a top-15 overall talent, but concerns about his arm length and overall size allow him to fall to No. 20. While Dallas has historically preferred longer cornerbacks, Delane’s instincts, ball skills, and coverage intelligence make him impossible to ignore at this spot.

With Daron Bland, Shavon Revel, and Mansoor Delane, the Cowboys would enter the 2026 season with three legitimate starting-caliber cornerbacks. Both Bland and Delane can operate effectively in the slot, giving the new defensive coordinator flexibility to disguise coverages and adjust matchups weekly.

This selection directly addresses one of the Cowboys’ most glaring weaknesses: defending the pass in critical moments.

Round 4, Pick No. 112: Austin Barber, OT, Florida

While defense dominates this mock draft, Dallas cannot ignore offensive line depth.

With Terence Steele potentially on the way out, the Cowboys need a developmental tackle who can step into a swing role early. Austin Barber fits that profile.

A three-year starter at left tackle for Florida, Barber is massive and powerful in the run game. While his pass protection technique remains a work in progress, his physical tools and experience make him a worthwhile Day 3 investment.

In the short term, Barber provides depth. In the long term, he could develop into a starter if properly coached.

Round 5, Pick No. 150: Bishop Fitzgerald, S, USC

Safety remains a quiet but critical need for Dallas, and Bishop Fitzgerald offers consistency and production.

Few defensive backs in the 2026 class have been as reliable as Fitzgerald over the past two seasons at USC. He plays with excellent anticipation, understands route concepts, and consistently puts himself in position to make plays.

Fitzgerald is expected to boost his draft stock at the Senior Bowl, and landing him at No. 150 would represent strong value for the Cowboys.

Round 5, Pick No. 177: Lake McRee, TE, USC

Tight end depth becomes increasingly important as Luke Schoonmaker approaches a contract year with little evidence of growth.

Lake McRee is not an inline blocker, but he offers something Dallas lacks at the position: athleticism. A fluid mover with strong hands, McRee profiles as a modern pass-catching tight end who can stress linebackers and safeties in coverage.

If the Cowboys eventually move on from Jake Ferguson, McRee could develop into a long-term solution.

Round 6, Pick No. 215: CJ Donaldson, RB, Ohio State

The Cowboys add competition to the backfield with CJ Donaldson, a unique offensive weapon.

A former tight end who transitioned to running back, Donaldson brings size, power, and pass-catching ability. He scored 10 touchdowns at Ohio State and 40 total touchdowns in his college career, while also recording 47 receptions.

With Phil Mafah struggling to stay healthy and contribute consistently, Donaldson could carve out a role as the No. 3 back and special teams contributor.

Round 6, Pick No. 211: Cole Payton, QB, North Dakota State

Dallas takes a late-round gamble at quarterback with Cole Payton, one of the most intriguing developmental passers in the class.

Though only a one-year starter at NDSU, Payton was highly efficient, averaging an eye-popping 12 yards per attempt. He possesses excellent deep-ball accuracy but needs significant refinement in reading defenses and handling pressure.

A year or two on the practice squad could unlock real value at minimal cost.

Round 7, Pick No. 225: Eric O’Neil, EDGE, Rutgers

The Cowboys close out the draft by reinforcing the defensive line once again.

Eric O’Neil has been one of the most productive edge defenders in the country over the last two seasons, totaling 28 tackles for loss and 15.5 sacks across stints at James Madison and Rutgers.

He projects as a rotational 4-3 defensive end with upside. His athletic testing will determine his ceiling, but on Day 3, the production alone is worth the risk.

Final Thoughts: A Defense-First Reset in Dallas

This 2026 mock draft reflects a clear organizational shift for the Dallas Cowboys: rebuild the defense from the ground up.

By investing early in the pass rush and secondary, while trusting young linebackers to develop internally, Dallas creates a foundation that can support sustainable success. The offense adds depth without sacrificing resources, and the defense gains youth, speed, and physicality.

If executed correctly, this strategy could move the Cowboys from the league’s worst defense back to respectability — and eventually, contention.

For Dallas, the road back begins in the trenches.
