The Defense Was Already Broken. Now It Has to Stop Saquon Barkley.

Two linebackers. That's the rotation Dallas is carrying into Monday night, and it isn't a depth chart so much as a prayer. Rashan Gary and Von Miller have split the linebacker snaps all season, with Curtis Robinson logging nothing meaningful behind them. DeMarvion Overshown, the player the organization pointed to all offseason as the answer to the linebacker void, was ruled out against Green Bay and remains a question mark. Dee Winters is out with an Achilles strain. The unit was thin before the injuries started; now it is skeletal in a way that would concern a coaching staff in any matchup. Against a healthy Saquon Barkley in a game Dallas cannot afford to lose, it is something closer to a structural crisis.

Barkley returning to practice this week after missing two games with a hamstring injury is the kind of news that changes a game plan. It should also change how clearly we see what Dallas's defense actually is. The secondary has been producing at roughly half of what you'd expect from a starting safety — Malik Hooker is the only safety logging meaningful snaps, and there is no viable option behind him. The linebacker corps is two-deep and already exposed. The pass rush carries no rotation depth behind the starters at either defensive tackle or defensive end — Quinnen Williams is the anchor up front, but the depth behind him has not produced. This is a defense that has been hemorrhaging points against competent offenses all season, and Philadelphia's offense, even without Jalen Hurts, is not incompetent.

What makes this matchup particularly punishing is the specific way Barkley stresses a defense like Dallas's. He does not just run between the tackles; he forces linebackers into space and punishes safeties who have to choose between the run and the pass. A two-linebacker rotation that has already been stretched thin is not built to contain that kind of backfield threat. Gary and Miller have to play every meaningful snap, and they have to do it against a back who spent the last two weeks watching film while Dallas was losing to Green Bay. The mismatch isn't subtle.

I wrote last week that Dallas had no answer for what Barkley's return meant. The piece ran before the game was played, and the argument was largely structural — this defense does not have the personnel to contain an elite back even at full health. Nothing that happened against the Packers changed that math. Dallas lost 13-23, the offense sputtered in the second half, and the defense generated no stops when it needed them. The team is now 2-4, sitting 1.5 games out of the last wild card spot with 11 games remaining. That margin sounds survivable until you recognize that this team has been outscored by 1.3 points per game all season and has not demonstrated the ability to win close games the way it did in stretches of 2025.

The Cowboys' close-game competence last season — that 57% win rate in games decided by a touchdown or fewer — has not carried over. The offense has the talent to keep games close; Dak Prescott, CeeDee Lamb, and Javonte Williams have all produced this season. But keeping a game close against Philadelphia only matters if the defense can hold Barkley to something manageable in the fourth quarter, and there is no evidence this unit can do that. A defense missing its third linebacker, operating with a safety producing at half the level the position demands, and carrying one-deep rotations at multiple spots along the line is not a defense that wins fourth quarters against top-tier backs. Monday night is going to show us exactly how much of the Cowboys' season has already been decided by the roster they built — or failed to build — before the first snap was ever played.
