What happened: NFL Network's Insiders projected a sharp defensive improvement for the Dallas Cowboys as the 2026 regular season opens. The forecast follows an offseason change in defensive approach.

Why it matters: Dallas has created $19 million in cap room, and Jerry Jones has said any trade would add to the defense. That leaves the unit's early performance tied to both the new scheme and the possibility of another move.

What to watch: The opening games will test the forecast while the trade market remains another route to reinforcement.
