What happened: The Cowboys added Kenny Clark, Quinnen Williams and Otito Ogbonnia to fortify the interior. Christian Parker replaced Matt Eberflus as defensive coordinator.
Why it matters: The acquisitions directly target a run defense the organization viewed as deficient. Dallas is banking on a rebuilt unit to lift it into NFC contention.
By the numbers: The coordinator search lasted 16 days and covered nine candidates. Philadelphia's pass defense moved from 30th to first in 2024 with Parker on staff.
What to watch: The opening weeks will test Parker's scheme and the reworked defensive front.
