4 Biggest Surprises From the Cowboys’ 2025 Preseason

The Dallas Cowboys are gearing up for a crucial 2025 campaign, and as always, preseason served as both a proving ground and a reality check. While the spotlight often shines on the stars, it’s the unexpected storylines that can shape a season.

From emerging rookies to depth-chart shakeups, here are the four biggest surprises the Cowboys revealed during this year’s preseason.

1. Rookie Running Backs Steal the Show 🏃💨

Few expected the Cowboys’ running back rookies to make headlines, but Jaydon Blue and Phil Mafah turned plenty of heads this summer.

• Jaydon Blue, the fifth-round pick from Texas, showcased the speed and receiving ability that Dallas desperately needs in its offense. Despite battling nagging injuries, his upside is undeniable, and he looks like a true playmaker once healthy.

• Phil Mafah, meanwhile, impressed with his physical, downhill running style that added a different dimension to the backfield. Unfortunately, a shoulder injury landed him on injured reserve, sidelining him for at least the first four weeks of the season.

👉 Surprise Factor: Instead of leaning only on veterans, the Cowboys may have stumbled upon rookie X-factors who could reshape the RB rotation in 2025.

2. James Houston Emerging as a Defensive Spark ⚡

The Cowboys’ pass rush lost a cornerstone when DeMarcus Lawrence departed, but James Houston is making a strong case as a disruptive edge presence.

Once considered a depth piece, Houston flashed explosive energy throughout preseason, consistently creating pressure and proving he belongs in the rotation. If he continues this trajectory, he could become one of the most underrated weapons in Dallas’ defensive arsenal.

👉 Surprise Factor: A supposed roster filler might just turn into a game-changer on defense.

3. Wide Receiver Depth Chart Gets Shaken Up 🎯

Entering camp, the expectation was that Jalen Tolbert would take a leap forward. Instead, Tolbert’s preseason was underwhelming, leaving the door open for others.

• Jalen Brooks and Ryan Flournoy capitalized, seizing their opportunities and impressing coaches with their consistency and playmaking.

This shift adds intrigue to Dallas’ WR group, which already leans on CeeDee Lamb as the focal point. If Brooks and Flournoy continue to shine, Tolbert may find himself sliding further down the depth chart.

👉 Surprise Factor: New names are emerging, giving the Cowboys unexpected WR depth heading into the season.

4. Zion Childress — A Rookie Cornerback Revelation 🛡️

One of the most pleasant surprises came from rookie cornerback Zion Childress, who stepped into a key role following Jourdan Lewis’ departure.

Childress excelled in slot coverage, showing quickness, physicality, and instincts beyond his years. In a secondary that already features Trevon Diggs and DaRon Bland, his emergence provides flexibility and security the Cowboys badly needed.

👉 Surprise Factor: Dallas may have found its nickel corner of the future in Childress.

Final Takeaway ✨

Preseason rarely tells the full story, but the 2025 edition offered some fascinating insights:

• The rookie RB duo of Blue and Mafah brought hope (and heartbreak).

• James Houston might be Dallas’ next defensive disruptor.

• The WR depth chart has been flipped upside down.

• And Zion Childress could be a hidden gem in the secondary.

For a team chasing consistency and a return to the postseason, these surprises could prove to be the difference between another disappointing year — or a breakthrough campaign.
