Which Dallas Cowboys rookie lit it up in his preseason debut?

The Dallas Cowboys’ preseason push toward a first 3-0 start since 2006 got a clear boost with linebacker Jaishawn Barham’s debut in Saturday’s 34-13 win over Arizona. Held out of the opener with a minor groin injury, Barham showed off in 18 defensive snaps, totaling five tackles, a tackle for loss, a quarterback pressure and a run stop. Coach Brian Schottenheimer praised his physicality while waiting to review film. The article notes Dee Winters remains listed as a starter ahead of Barham for now, though Sports Illustrated suggests Barham’s early impact could change that. It also highlights Shiyazh Pete as the first Navajo to play an NFL preseason game, using a viral postgame breakdown.
