What happened: Dallas is already adjusting the back end of the roster after Sunday's 28-20 defeat. The Cowboys signed Tyler Goodson to the active roster Friday after placing Malik Davis on injured reserve earlier this week and waiving Israel Abanikanda in the corresponding moves.
Why it matters: The shuffle puts extra focus on how quickly Dallas stabilizes its depth after an early stumble. Jerry Jones said this week he expects improvement from the defense, raising the pressure for a cleaner showing next time out.
By the numbers: Goodson was signed to the active roster on Sept. 18 after joining Dallas on Sept. 15. Davis went on injured reserve Sept. 12, and Abanikanda was waived in the corresponding move.
What to watch: Dallas' next depth chart and inactives will show whether the backfield changes stop here. The bigger test is whether the defensive improvement Jones predicted shows up immediately.
