Quinnen Williams joined the Dallas Cowboys for seven forgettable games in 2025 following his trade deadline deal. Even with the four-time Pro Bowler, the Cowboys defense stunk up the joint last season.
In the months since, the 28-year-old has seen a distinct turnaround under new defensive coordinator Christian Parker.
"The growth, it's like night and day," Williams said of the strides made by the Cowboys on defense, via the team's official website. "Starting in OTAs, and starting the first week of training camp, getting a chance to go against one of the best offenses in battle every single day has helped us tremendously. The mindset coming from the coaches, top down to the players and to the leadership, has been drastically changed. It's just fun, man.
"I just can't wait to see the process and the results from all the hard work, but we're not done yet."
The Cowboys moved on from a stale Matt Eberflus and imported Parker, who has worked under Vic Fangio and brought over a modernized scheme. They buffered the new DC with improved talent, trading for Rashan Gary and Dee Winters, signing Jalen Thompson, Cobie Durant, P.J. Locke and Von Miller, and drafting potential difference-makers in Caleb Downs, Malachi Lawrence and Jaishawn Barham.
Williams believes that not only will the upgraded talent ignite an improved defense, but facing one of the most dynamic offenses in the NFL in daily practices also aids the ascension.
"The last time I kind of felt this was when I was at 'Bama, when it came down to you going against first-rounders across from you," he said. "But here in the NFL, it's All-Pros everywhere, getting a chance to go against one of the best offenses in the league and one of the best quarterbacks in the league.
"And we've got one of the best offensive lines in the league, so using them as a helping tool to get better every single day, and the urgency level from a defensive standpoint to get better every single day. It's been well-needed and fun. It's definitely a battle."
On paper, the Cowboys D looks legit. We've been fooled by paper oracles in the past. The real test begins in prime time on Sept. 13 against the New York Giants.
