Are the Dallas Cowboys set for a crashing success or just a crash landing in 2026? They sure did not spend the offseason making subtle moves. Major upgrades and aggressive roster-building dominated the headlines. Yet if Dallas is going to transform from a playoff contender into a legitimate Super Bowl threat, the biggest difference-makers may not be the stars everyone is talking about. Two names stand out as prime breakout candidates entering the 2026 season. Linebacker DeMarvion Overshown has the opportunity to become the heartbeat of Christian Parker’s new defense. Wide receiver Ryan Flournoy appears perfectly positioned to capitalize on favorable matchups within one of the NFL’s most dangerous passing attacks.
Reshaped their identity

The Cowboys engineered one of the league’s most aggressive roster transformations during the 2026 offseason. The front office wasted little time making major moves. Dallas traded significant draft capital to acquire edge rusher Rashan Gary. The organization also placed the franchise tag on wide receiver George Pickens.
Free agency provided additional reinforcements. Safety Jalen Thompson, cornerback Cobie Durant, and quarterback Sam Howell joined the roster. Javonte Williams received a three-year extension after proving to be a valuable piece of the offense.
The Cowboys were not finished. During the 2026 NFL Draft, they traded up to secure Ohio State standout Caleb Downs. Afterward, they maneuvered back into the first round for edge defender Malachi Lawrence.
Taken together, the moves represented a dramatic commitment to toughness, versatility, and defensive dominance. However, Dallas still needs internal development from emerging contributors if it hopes to compete with the NFC’s elite.
LB DeMarvion Overshown
Few players on the Cowboys roster possess a higher ceiling entering 2026 than Overshown. His story has already been defined by resilience. Injuries slowed his early development. Yet whenever Overshown has been healthy, he has flashed the type of athleticism that defensive coordinators covet.
His production during his rookie season in 2024 was eye-opening. Overshown recorded 90 tackles, five sacks, and a defensive touchdown. More importantly, he demonstrated the rare sideline-to-sideline range that allows modern linebackers to thrive. In 2025, he was limited to six games. Now, he enters 2026 fully healthy and positioned to take over the MIKE linebacker role in Parker’s new 3-4 system.
The supporting cast around him only strengthens his breakout case. Williams and Kenny Clark form one of the NFL’s most imposing interior duos. Gary provides an elite edge presence capable of collapsing pockets and forcing offenses into difficult situations. Opposing offensive lines will have their hands full simply trying to survive the trenches.
That should create cleaner paths to the football for Overshown. Instead of consistently fighting through traffic, he will have greater freedom to attack downhill. Parker’s scheme also places a premium on linebackers. Overshown possesses the athletic profile to handle coverage responsibilities while remaining an effective run defender. If he stays healthy for a full season, surpassing 120 tackles is entirely realistic.
WR Ryan Flournoy
Ryan Flournoy has a legitimate chance to become one of the NFL’s most productive third receiving options. The attention surrounding Dallas’ passing game naturally centers on CeeDee Lamb and George Pickens. Yet that star power creates opportunities elsewhere.
Flournoy quietly put together an encouraging 2025 season. He recorded 40 receptions for 475 yards and four touchdowns while steadily earning Prescott’s trust. Those numbers provided a strong foundation for future growth. Now, Flournoy enters the season with a clear path to becoming Dallas’ primary third receiver.
At 6-foot-2 with impressive acceleration and strong ball skills, he possesses the traits necessary to punish defenses. He is particularly dangerous on intermediate routes, where his combination of size and burst can create separation against nickel corners and safeties.
The Cowboys do not need Flournoy to become a Pro Bowler. They simply need him to consistently win favorable matchups. If he accomplishes that, his numbers could rise dramatically. A season of 60-plus catches, 800 yards, and several explosive touchdowns is well within reach.
Why sleepers matter

The Cowboys have assembled a roster capable of competing with anyone in the NFC. They possess elite talent on both sides of the ball, a veteran quarterback, and a defense that looks significantly more formidable than before.
However, championships are rarely won by stars alone. They are won when role players become difference-makers. Overshown has the talent to transform into one of the league’s most impactful linebackers. Flournoy is perfectly positioned to take advantage of the attention commanded by Dallas’ superstar receivers.
If both players realize their potential, the Cowboys will suddenly become deeper, more dangerous, and far more difficult to defend. That type of internal breakout could prove just as valuable as any blockbuster acquisition made during the offseason.
