What happened: The Dallas Cowboys have cycled through four defensive coordinators across the past four seasons, leaving quarterback Dak Prescott as the constant anchor for the franchise. The turnover underscores recurring defensive changes in Dallas while the offensive core remains centered around Prescott.

Why it matters: Dallas sits at 3-5 through eight games in 2026, holding the 13th seed in the NFC following a 33-30 loss to the Arizona Cardinals. Continued defensive volatility places added pressure on Prescott and the scoring unit to outpace defensive concessions during the second half of the season.

What to watch: Dallas faces the Nov. 10 NFL trade deadline as the front office evaluates potential roster upgrades to stabilize the season.
