Cowboys sign Von Miller as running back competition unfolds

The Dallas Cowboys signed outside linebacker Von Miller following their preseason win against the Seahawks. Miller's presence aims to enhance a defense that conceded only one score on the opening drive. Meanwhile, the running back competition remains intense, with Malik Davis impressing during the preseason opener. The Cowboys are set to face the Arizona Cardinals in their next preseason game, where linebackers Jaishawn Barham, Zion Childress, and Devin Moore are expected to return to practice.
