Cowboys news: Dallas defense playing faster under Christian Parker

Dallas hit the practice field on Wednesday, and rookie linebacker Jaishawn Barham and cornerback Shavon Revel Jr. got some snaps with the starters. The final preseason for the Cowboys is on Friday, and the unofficial depth chart came out.

The Cowboys are looking to be a much more effective defense in 2026. According to DeMarvion Overshown , Christian Parker's scheme is letting them play with more speed.

Over the course of the last few months, Overshown has seen Dallas' defense grow the most in trusting what they see. In his eyes, Parker, who was heralded by the Cowboys front office and Brian Schottenheimer as a great teacher when he was hired as defensive coordinator, has passed along his lessons in a way that all 11 players on the field know their jobs and the jobs of those around them.
