How the Cowboys’ 2026 rookies fared in the preseason: highs, lows, and who’s earned trust

Thelandryhat reviewed each Dallas Cowboys 2026 draft pick following the preseason and the team's final 53-man roster announcement. The review finds several early success stories among the rookies, some clear situational upside, and at least one pick who remains a project.

Downs, the Ohio State defensive back who fell into Dallas' lap in the draft, is the piece most consistently praised. He's expected to start in the nickel and already has earned coaching trust to line up across the defensive backfield. The review calls him a realization of the role scouts envisioned and suggests his immediate ceiling is high even if elite play won't be instantaneous.

Barham's preseason work produced very strong PFF marks and reps with starting personnel. Thelandryhat highlights both his traditional linebacker impact and his versatility as an edge rusher and stand-up off-ball option. His early usage and high grades indicate he's more than a special-teams or fringe depth piece entering the regular season.

Shelton's preseason performance is described as poor enough that his roster spot could have been in doubt. The Cowboys nonetheless kept the fourth-round offensive tackle on the 53-man roster despite additional offseason moves at the position. The takeaway: Shelton's athletic traits still exist, but he's a developmental gamble who should not be expected to contribute early in 2026.

Roster context and coaching implications

The article frames the rookie grades inside Dallas' broader roster work. Several top picks already look like robust pro players and helped shape the final depth chart. At the same time, Brian Schottenheimer and the coaching staff have identifiable monitoring points — particularly among young offensive linemen and any rookie whose preseason tape included clear mistakes. The signing of Von Miller affects how snaps and opportunities are allocated among rookie edge options.

• Downs' snap usage and matchup assignments in nickel packages will reveal how quickly he can hold up against NFL route concepts and physical NFL receivers.
• Barham's early-game reps and special-teams role will indicate whether his preseason production translates to Week 1 availability in high-leverage situations.
• Lawrence's role behind veteran additions will show whether the team plans to develop him slowly or rotate him into meaningful pass-rush reps.
