The Cowboys allowed 4.9 yards per carry in 2025, ranking 28th in the NFL per Pro Football Reference. This was not a talent problem — it was a scheme and alignment problem. Let me show you what happened.
The core issue: One-gap vs. two-gap confusion The Cowboys defensive line was asked to play a hybrid scheme that alternated between one-gap and two-gap responsibilities depending on personnel grouping. Film study shows the interior linemen were frequently misaligned, creating gaps that running backs exploited.
By the numbers:
- Runs up the middle: 5.2 YPC allowed (31st in NFL). Source: ESPN Stats and Info.
- Runs off-tackle: 4.4 YPC allowed (18th — acceptable)
- Outside runs: 3.8 YPC allowed (10th — actually good)
The problem was concentrated between the tackles. When teams ran directly at the A and B gaps, Dallas had no answer.
The Parsons factor: Micah Parsons is an elite pass rusher but his run defense grade per PFF was 58.4 in 2025. When he is on the field, the defense is designed around getting him to the quarterback. That creates inherent trade-offs against the run because his edge-setting discipline takes a back seat to his rush plan.
What the solution looks like:
- Draft a true nose tackle who can eat double teams (addressed in the 2026 draft)
- Commit to a one-gap scheme full-time — stop confusing the interior linemen
- Use Parsons more selectively on early downs to preserve run integrity

The nose tackle pick in round 3 of the draft directly addresses this. A 310-pound space eater who can hold point of attack. Exactly what we needed.
