The Dallas Cowboys are gearing up for the 2025 season with a revamped defense, sparking excitement and curiosity among fans. After a lackluster performance last year, the team has made significant changes, bringing in new coaches and players to reshape their defensive identity. But where exactly have the Cowboys improved, and where might they still face challenges? Let’s dive into a position-by-position analysis to uncover the strengths and concerns for this upcoming season, as inspired by Dan Rogers’ recent breakdown on Blogging The Boys.

Edge Rushers: A Mix of Stability and Promise
At EDGE1, Micah Parsons remains the cornerstone of the Cowboys’ defense. As one of the NFL’s premier pass-rushers, Parsons’ elite performance is a constant, with no changes expected. His dominance ensures this position remains a strength, and with a lucrative contract on the horizon, he’s poised to continue wreaking havoc.
EDGE2 sees a shift with Dante Fowler stepping in. While losing DeMarcus Lawrence, a reliable veteran, stings, Fowler’s double-digit sack season last year suggests he’s a quality pass-rusher. Compared to the rotational duo of Carl Lawson and Chauncey Golston, who filled in during Lawrence’s injury, Fowler’s addition marks a slight improvement, particularly in pass-rushing prowess. The depth of the edge group, with constant rotations, further bolsters this area.
Defensive Tackles: Steady Progress
The 3-TECH position remains unchanged with Osa Odighizuwa, a standout defensive tackle whose recent contract extension secures his role. His consistent disruption and long-arm technique make this spot a non-issue for Dallas.
At nose tackle, Mazi Smith continues to develop. With 42 tackles last season—the most by a Cowboys nose tackle since 2015—Smith shows gradual improvement at just 23 years old. While optimism surrounds his growth, the analysis keeps expectations grounded, labeling this position as no change to avoid overhyping potential.
Linebackers: A Mixed Bag
The linebacker corps presents both promise and concern. Marist Liufau at SAM had a solid rookie year, with 50 tackles and 1.5 sacks across 17 games. His time learning from veteran Eric Kendricks should fuel further growth, earning this spot a slight improvement.
However, the MIKE position sees a slight decline with Jack Sanborn replacing Kendricks. Kendricks, at 32, delivered a stellar 138 tackles, three sacks, and three forced fumbles last season. Sanborn, a 24-year-old undrafted free agent, is a capable player with upside, especially under new defensive coordinator Matt Eberflus, his former coach. Still, replacing Kendricks’ production is a tall order.
The WILL position also takes a hit with Kenneth Murray stepping in for DeMarvion Overshown, who was sidelined by another knee injury. Overshown’s 90 tackles and five sacks last season showcased his star potential, while Murray, despite his athleticism, doesn’t match that playmaking flair, resulting in a slight decline.
Cornerbacks: Uncertainty Looms
The cornerback group is riddled with questions. Trevon Diggs at CB1 is coming off another knee injury, and his 2024 performance was lackluster compared to his earlier playmaking days. With recovery uncertainties, this position is marked as no change, though rookie Shavon Revel Jr. could provide a late-season boost.
DaRon Bland at CB2 offers hope. After missing 10 games last season, Bland is now healthy and in a contract year. His versatility and potential to recapture his record-breaking form (five pick-sixes in 2023) make this a slight improvement.
The CB3 slot, however, is a clear decline. Losing Jourdan Lewis to free agency hurts, as his subtle but valuable contributions are hard to replace. Kaiir Elam, a former first-round pick acquired via trade, is a reclamation project with inconsistent flashes, leaving this position vulnerable.
Safeties: Consistency Holds
Donovan Wilson at strong safety is a polarizing figure, capable of both brilliance and mistakes. With his contract nearing its end and the team extending other safeties like Markquese Bell, Juanyeh Thomas, and Israel Mukuamu, this position remains no change, though Wilson’s roster spot isn’t guaranteed.
Malik Hooker at free safety continues to be a reliable veteran, playing at least 15 games each of the past four seasons. His steady presence ensures no change here, providing a stabilizing force in the secondary.
The Cowboys’ defense in 2025 is a blend of elite talent, cautious optimism, and lingering concerns. Standouts like Micah Parsons and Osa Odighizuwa anchor the unit, while Dante Fowler and DaRon Bland offer exciting upgrades. However, losses at linebacker and the nickel corner, combined with uncertainty around Trevon Diggs, raise red flags. As fans eagerly await the season, the question remains: can these changes propel the Cowboys to a stronger defensive showing, or will the weak spots hold them back?
