"We haven't been up to par": Brian Schottenheimer blasts Cowboys' "unacceptable" execution after Week 1 disaster

The Dallas Cowboys entered their 2026 season opener expecting a fresh start. Instead, their first game under a heavily revamped defense exposed many of the same issues that had plagued the team previously.

A 28-20 defeat to the New York Giants at MetLife Stadium left head coach Brian Schottenheimer openly frustrated with the Cowboys ' execution, as Dallas struggled to establish the run, contain New York's rushing attack and avoid costly mistakes.

The loss also gave new Giants head coach John Harbaugh a victory in his first regular-season game with the franchise.

Schottenheimer did not attempt to disguise his frustration with the performance.

"Not good enough on either side of the ball. We gotta do a better job running the ball, stopping the run. The penalties aren’t good enough. Too many drops. We’ll get going. A lot of things to clean up," Brian said, according to The Athletic reporter Jon Machota .

That assessment summed up a night in which Dallas repeatedly made life harder for itself. The Cowboys were penalized heavily early, while their offense struggled to find consistency against a Giants defense that generated pressure without needing to rely on aggressive blitz packages.

The problems were particularly concerning because expectations had been raised considerably during the offseason.

Dallas had made significant changes to its defense after a poor 2025 campaign, appointing Christian Parker as defensive coordinator and adding new personnel in an effort to create a more aggressive and reliable unit. NFL.com had identified the revamped defense as one of the central storylines heading into the opener.

Instead, Jaxson Dart and the Giants offense controlled long stretches of the game. Dart completed 23 of 29 passes for 230 yards and three touchdowns while adding 54 rushing yards, while New York finished with 165 rushing yards and controlled possession for more than 36 minutes.

Dallas also had problems protecting Dak Prescott . The quarterback finished the game with 175 passing yards, two touchdowns and an interception, with the Giants repeatedly creating pressure with their front four.

Cowboys' biggest concerns go far beyond one bad night

One of the clearest problems entering the game was the condition of Dallas' offensive line. Three-time Pro Bowl guard Tyler Smith had been placed on injured reserve after thumb surgery, forcing T.J. Bass into the starting lineup. NFL.com had already highlighted Smith's absence as a major concern before kickoff.

The Giants were more than willing to test that weakness. Brian Burns had already suggested that Dallas' situation at right tackle could provide an opening for New York's pass rush.

"Not to disrespect anybody’s craft or anything like that," Burns said via Pat Leonard of the New York Daily News.

"But the fact that they are so concerned in that area does, I guess, raise some form of an alert in our minds, as far as like just knowing that they’re having struggles. . . . So we can definitely see that as an opportunity to exploit."

New York did precisely that, with Burns and Kayvon Thibodeaux helping create pressure that prevented Prescott from consistently settling into the pocket.

The struggles also prevented Dallas' expensive-looking receiver combination from taking over. George Pickens had entered the season alongside CeeDee Lamb with enormous expectations and had previously declared: "Yeah, we definitely think we’re the best."

The Giants did not allow the pair to dominate. Lamb did score a touchdown, but Dallas' passing game lacked the explosiveness expected from the new-look offense.

Pickens was particularly frustrated by dropped opportunities, including a deep Prescott pass that went through his hands on a potentially important drive.

The result was a statistical performance that fell well short of the Cowboys ' expectations.

Defensively, the concerns were just as significant. Christian Parker 's first game in charge of the Dallas defense ended with the Giants scoring 28 points and consistently sustaining drives.

Isaiah Likely was particularly damaging, catching eight passes for 78 yards and two touchdowns, while Skattebo added a rushing score.

Schottenheimer therefore has plenty to address before Dallas returns to action. The Cowboys were not simply beaten by a handful of spectacular plays; they were repeatedly undone by penalties, missed opportunities, poor execution and an inability to control the line of scrimmage.

The encouraging part for Dallas is that this was only Week 1. The season is long enough for Parker's defense to develop, the offensive line to adjust and Prescott's supporting cast to find its rhythm.

But the standard is considerably higher in Dallas, and Schottenheimer knows it.

After an offseason built around fixing the problems that contributed to last year's disappointment, the Cowboys delivered an opening performance that suggested the work is far from finished.
