The Dallas Cowboys’ defense has to be a different animal in 2026. After finishing as the worst unit in the NFL and helping keep Dallas out of the playoffs, this group is going to be under the microscope from the start. And in a set of predictions for every defensive position group, there’s a clear theme: a couple of starters are headed for Pro Bowl recognition, one projected starter loses his job, and two young players take a real step forward.
One of the biggest swing factors is Kenny Clark. He hasn’t been at the same level in recent years that he reached earlier in his career, but the setup for 2026 gives him a chance to get back there.
Clark is at his best as a 3-4 nose tackle, even though he hasn’t played that role regularly since 2021. That changes in Christian Parker’s defense, where he’s expected to return to the spot he calls home.
"I pride myself on being an all-around defensive tackle, but I'm primarily a nose tackle. That's my bread and butter," he said in 2025.
That matters because two of Clark’s three Pro Bowl selections came in seasons when he was lining up at nose tackle more often. The prediction here is that getting back to his “bread and butter” leads to Pro Bowl No. 4.
There’s also a big leap forecast for Donovan Ezeiruaku. The second-round pick only had two sacks last season, but the underlying production was a lot more encouraging: 12 quarterback hits and 36 pressures, numbers that ranked second and tied for third among rookies, according to Pro Football Focus.
That kind of pressure usually turns into sacks sooner or later, and the expectation is that 2026 is when Ezeiruaku starts cashing in more often. With offenses paying extra attention to Rashan Gary and whatever else Parker throws their way, Ezeiruaku is projected to lead Dallas in sacks.
Another name on the rise is DeMarvion Overshown, and the prediction comes with a major caveat: health. The former third-round pick has dealt with a pair of significant knee injuries across his first three NFL seasons and has appeared in only 19 games.
Still, the belief here is that a contract year finally brings a full season and a Pro Bowl level of play. The catch?
That kind of year would likely price him out of Dallas, setting him up to play somewhere else in 2027.
The secondary could also look different by the end of the season. The expectation is that Revel and Bland open the year as the Cowboys’ boundary starters, but at least one of them won’t hold onto the job.
Both were ineffective last season, and Bland’s issues have stretched over two years while health has been a problem as well. Cobie Durant was added as insurance, and the prediction is that Dallas eventually turns to him as a starter.
The pick here is that Bland gets replaced, while Revel rebounds in his second season removed from a torn ACL.
And then there’s Caleb Downs, who arrives with the kind of buzz that usually comes with a can’t-miss prospect. He was widely seen as a blue-chip player before the draft, and nothing in OTAs or minicamp has cooled that off.
In fact, he kept getting more responsibility as the offseason went on, which points to a smooth early transition. Downs is expected to make an immediate impact as both a safety and nickel corner in Dallas’ revamped defense, and the prediction is that he finishes top three in Defensive Rookie of the Year voting.
A safety hasn’t won the award since 1990, when Mark Carrier did it, so even that kind of finish would be a notable first-year achievement.

Commanders Just Twisted The Knife On Cowboys' Biggest Secondary Concern
The Commanders kept building out their secondary by adding veteran cornerback Rasul Douglas on a deal reportedly worth $3.8 million, a move that gives Washington another experienced body in a room that still has its own questions. Douglas has been around the league enough to know the job, with stops that include Green Bay and Miami, and his arrival is the sort of depth signing teams make when they want a steadier floor on the back end.
For Dallas, the timing lands with a little more sting because the Cowboys are already dealing with uncertainty at corner. Health concerns around DaRon Bland and Shavon Revel have made the position a real watch item, and the depth behind them is thin enough that every outside move in the division feels a little louder than it otherwise would. In a race where secondary stability matters, Washington just made sure it has one more option while the Cowboys are still sorting out theirs. [Read more 🡒]
Cowboys Linked To Veteran Answer For A Defense That Needs One
The Cowboys linebacker room remains one of the cleaner places to look for help on a defense that still needs it, and a veteran option has surfaced as a logical fit. Bobby Wagner is coming off another productive season, showing he can still handle a full workload and bring the kind of steadiness that teams lean on when the middle of the defense needs sorting out.
Dallas has at least one added wrinkle here, too, because Brian Schottenheimer already knows Wagner from their Seahawks days. Even so, this is still more of a fit check than a transaction report, with the Cowboys linked to the idea of adding a proven linebacker but no move actually in hand yet. [Read more 🡒]
New Findings On Marshawn Kneelands Death Will Hit Cowboys Fans Hard
Marshawn Kneelands death has already left the Cowboys community grieving, and the latest findings add another painful layer to remember about the former defensive lineman. The Boston University CTE Center examined his brain tissue, and the Concussion & CTE Foundation later announced a posthumous diagnosis of Stage 1 chronic traumatic encephalopathy, a condition tied to repeated head impacts and one that can only be identified after death through neuropathological examination.
Kneeland was just 24 when he died, and the news is especially sobering for a player whose NFL career had only just begun to take shape. His family donated his brain tissue for the examination, and the foundation has emphasized that the diagnosis should not be read as a cause of death or a proven suicide risk factor, a distinction that matters even as the football world keeps confronting the long-term toll of the game.
