The Dallas Cowboys’ defense showed signs of progress but remains a work in progress after their 34-30 victory over the Houston Texans on Sunday. The game highlighted ongoing challenges, particularly in containing key offensive threats and applying consistent pressure on opposing quarterbacks.

Houston’s wide receiver Nico Collins, returning from a hamstring injury, emerged as the primary issue for Dallas’s defense. Collins turned a simple route on the Texans’ opening play into a 45-yard gain and later scored a touchdown on a 7-yard reception. He finished the game with seven catches for 118 yards and two touchdowns, marking the fourth multi-touchdown game in his six-year career. Cowboys head coach Brian Schottenheimer acknowledged the team’s failure to limit Collins and noted that Houston quarterback C.J. Stroud targeted him when the newly acquired cornerback Joey Porter Jr. was not on the field.

Despite trailing 16-6 at halftime, the Cowboys rallied in the second half to secure the win. The defense made a crucial stop late in the game after a game-winning touchdown pass from Dak Prescott to CeeDee Lamb with 40 seconds remaining. Houston was held to three of 10 conversions on third down in the second half, but Dallas’s defense still surrendered eight plays of 20 yards or more and allowed an average of 7.6 yards per play.

The Cowboys' defensive unit has improved marginally since Week 1, particularly with better communication compared to last season. Defensive tackle Quinnen Williams and his group have found their footing over the past two games, and edge rusher Rashan Gary recorded his first sack for Dallas, leading the team with two quarterback hits. Rookies Caleb Downs and Jaishawn Barham have also shown promise. The recent trade to acquire Porter is expected to bolster the defensive backfield further, especially if safeties Malik Hooker, Jalen Thompson, and P.J. Locke return to full health.

Nevertheless, major concerns persist. Opposing quarterbacks have thrived against Dallas, posting a combined passer rating of 122.7 over four games—the highest in the NFL. They have thrown nine touchdowns without an interception, and Dallas has managed only four sacks, tied for the second-fewest in the league. The pass rush remains inadequate, prompting Cowboys executive vice president Stephen Jones to acknowledge the possibility of pursuing additional edge rushers to strengthen the defense.

Schottenheimer praised his team’s effort following the game, highlighting solid third-down and run defense despite allowing too many explosive plays. He admitted the pass rush was inconsistent and that opposing quarterbacks, like Stroud, appeared comfortable through much of the contest, particularly in the first half.

On offense, Dallas continued its strong start to the season with standout performances from quarterback Dak Prescott, wide receivers CeeDee Lamb and George Pickens, and running back Javonte Williams, who has tallied six touchdowns. The offensive line is expected to improve with the potential return of Pro Bowl guard Tyler Smith, raising hopes that the offense can carry the team even if defensive struggles persist.

While the Cowboys could win nine to 10 games relying heavily on their offense, their defense will need considerable improvement to compete deeply in the playoffs. Dallas has not held an opponent to fewer than 14 points since Week 18 of the 2023 season and suffered a decisive 48-32 wild-card loss to the Green Bay Packers. Schottenheimer remains optimistic but acknowledges the defense's long road ahead to becoming a reliable unit capable of winning tight, high-stakes games.
