The New York Giants open the 2026 NFL season on Sunday Night Football against the Dallas Cowboys, and the defensive side of the ball presents serious concerns heading into Week 1.

Dak Prescott, CeeDee Lamb, and George Pickens form one of the most dangerous passing attacks in the league, and the Giants’ cornerback room remains one of the most unsettled position groups on the roster. 

The Cowboys’ passing attack is terrifying

Prescott is undoubtebly a reliable quarterback. Last season, he threw for 4,500 yards, 30 touchdowns, and 10 interceptions. More importantly, he’s throwing to a wide receiver tandem that has become one of the most dangerous in football. George Pickens went for over 1,400 yards last year. CeeDee Lamb, despite dealing with injuries, still eclipsed 1,000 yards while drawing the lion’s share of defensive attention.

This matchup feels so daunting because of the uncertainty surrounding the Giants’ secondary. It’s unclear whether the outside tandem will feature Paulson Adebo, Greg Newsome, Deonte Banks, or Colton Hood. The fact that this remains one of the most unsettled positions on the team heading into a primetime opener is concerning. 

Reports throughout camp have indicated that Adebo has stagnated rather than stepping up as the prized free-agent signing ready to dominate on the outside under the new regime. Newsome and Banks could end up as the outside starters. Trying to figure out who the starting corners are while simultaneously facing Pickens, Lamb, and Prescott is a brutal way to open the season.

The pass rush has to carry the defense

Where the Giants can produce success and make big plays is getting after Prescott. The Cowboys’ offensive line is stellar overall, but their weakest spots are at tackle. Terrence Steele has been the weakest link of the group, and Tyler Guyton has been extremely up and down since Dallas drafted him a few years ago.

There’s a real opportunity for Brian Burns, Abdul Carter, and Kayvon Thibodeaux to get creative and aggressive against this tackle pairing. If the Giants want to win this game and slow down a Cowboys passing attack that put a comical amount of points and yards on them during last year’s early-season matchup, they need impressive sack production from the pass rush trio.

They can’t come out of this game with two or three sacks. This needs to be a dominant performance. With a matchup against the two weakest links on the Dallas roster, the advantage tilts toward New York’s edge rushers. Forced turnovers, strip sacks, and disrupted pockets would give the offense short fields and keep the Cowboys’ offense off the field.

The interior defensive line is a massive question mark

The most glaring concern on the defensive side might be the Giants’ interior defensive line and a total lack of clarity on whether they have enough talent to stop opposing rushing attacks. The Giants got run over during the preseason, and lingering questions remain about DJ Reader’s readiness, CJ Okoye’s role, whether Darius Alexander can improve, and whether Shelby Harris can fill be impactful.

Those questions matter because the Cowboys ranked 4th lowest in run stuff rate allowed last season. That was arguably their best statistical category. Javonte Williams ran for over 1,200 yards and 11 touchdowns behind that group.

Something to capitalize on: The Cowboys will be playing backup T.J. Bass in place of All-Pro left guard Tyler Smith, who is going on IR with a thumb injury.

If the Giants get run over early in the first quarter and Reader’s group can’t generate penetration and secure early-down stops, this game could be over before it starts.

The linebackers could be the X-factor

One intriguing element is that Dallas’ interior linemen are a power-based group without elite speed. Beebe isn’t particularly fast and Booker tested on the slower side at the NFL Scouting Combine. The Giants could have an underrated edge with Tremaine Edmonds and Arvell Reese, who are super fast and fly all over the field. Those two have the juice, speed, and instincts to make plays at the line of scrimmage. All they need is for Reader and the rest of the defensive tackle group to hold their ground long enough to let the linebackers attack.

New York’s biggest challenge in this game is slowing down the Cowboys’ offense. The best path to victory involves controlling the pace of the game and keeping Dallas off the field through long, methodical drives. If the pass rush can dominate the tackle matchup and the linebackers compensate for whatever the interior defensive line can’t provide, the Giants give themselves a chance.

If neither happens, it’s going to be a long night in primetime.
