The Cowboys are about to open training camp in Oxnard, and one of the biggest storylines on defense is how Christian Parker’s new look will take shape. With a little more than two weeks to go before practice starts, Dallas is getting ready to show off a revamped unit under its new defensive coordinator, and Parker has already made his presence felt in the way the roster has been built around his scheme.
At the center of that picture is DeMarvion Overshown. The fourth-year linebacker looks like the leading candidate to handle the quarterback role in Parker’s defense and wear the “green dot,” and he’s expected to play a major part in the team’s hybrid 3-4 setup.
There’s also real buzz around what Overshown can become if he can finally put the injury issues behind him. In a recent poll of NFL executives and coaches, he earned an honorable mention among the league’s top linebackers, a sign that people around the league are paying attention to his upside.
Health has been the obstacle from the start. Overshown lost his entire rookie season after tearing his ACL in the preseason, then came back with a strong opening to 2024 before another devastating setback ended that run in early December. That injury included tears to his ACL, MCL, and PCL, and the damage was serious enough to keep him out for most of the 2025 season.
Now he enters the offseason healthy, and that matters for a player whose best chance to make his mark comes in Parker’s system. One NFC scout didn’t hide the appeal of Overshown’s talent, saying, "He moves like a safety.
Incredibly talented. I want to see how he does this year after the injuries,"
If Overshown can stay on the field in 2026, the Cowboys may finally get the version of him they’ve been waiting to see. When he’s right, he has the kind of game that can change what Dallas’ defense looks like.

Former Cowboys Quarterback's Comeback Took An Unexpected Turn
Will Griers latest NFL stop was supposed to be a familiar one, with the quarterback back in Carolina earlier this offseason after previous time with the Panthers. Instead, the comeback has already taken a sharp turn, and the move closes the door on a career that also included two separate stints with the Cowboys, giving Dallas fans at least a passing connection to a player whose journey never quite settled in one place.
For Carolina, the timing matters because the quarterback room is now down to Bryce Young, Kenny Pickett and rookie Haynes King heading toward training camp. Griers departure removes another experienced option from the mix and leaves the Panthers to sort out their depth and pecking order without the veteran presence they had just brought back into the fold.

George Pickens Just Sent A Clear Message In Cowboys WR Debate
George Pickens gave the Cowboys exactly the kind of production that can tilt a wide receiver conversation in his favor. In his first season with Dallas, he finished third in the NFL in receiving yards and added nine touchdowns, the sort of output that makes it hard to argue he was merely along for the ride in the offense.
Stefon Diggs, meanwhile, is back on the open market after a year with the New England Patriots, and his claim to being the leagues best No. 2 receiver is getting a harder look. The comparison does not seem to be breaking in his favor, and for Dallas, that only adds another layer to a receiver debate that already has plenty of bite. [Read more 🡒]
Tyler Booker Has One Hurdle Left Before Joining The NFL Elite
Tyler Bookers first NFL season gave the Cowboys a pretty clear reason for optimism. The rookie interior offensive lineman drew notable praise in a survey of NFL executives, coaches and scouts, landing in the honorable mention tier just outside the top 10 at his position after showing the kind of strength and athleticism that can make him a long-term anchor inside.
The next step is more specific, and it is the one that will determine whether Booker gets mentioned with the leagues best. He has to clean up the way he handles interior linemen who move well laterally, because that is where some of the rougher moments showed up in 2025 and where the gap still separates him from the top tier. If the agility and technique come along, Dallas may have one of the NFLs better young building blocks in the middle of its line. [Read more 🡒]
