Cowboys seek left-tackle stability as roster questions linger on the blindside

The Dallas Cowboys are still searching for consistent answers at left tackle, a position that has become the most visible construction issue on an offense built around protecting the quarterback and sustaining timing up front. As the team moves through the offseason and toward training camp, the Cowboys’ priority is not a theoretical solution. It is finding a player who can win the job and stay there long enough for the unit to function as a dependable whole.

The most discussed name remains Tyler Guyton, the 2024 first-round tackle the Cowboys selected with their approach to long-term offensive-line continuity in mind. Pro Football Rumors reports that Dallas has been looking for Guyton to establish himself over the past two seasons, but evaluation and availability have stalled that progress. The report notes that Pro Football Focus graded Guyton 73rd among 81 tackles in 2024 and 67th among 84 tackles in 2025.

Part of the concern, according to the same report, has been that Guyton has had difficulty staying on the field. Pro Football Rumors describes how he opened his rookie season as the starter after Chuma Edoga missed time in the preseason, only to be forced around by knee and shoulder injuries that disrupted practice. The situation shifted again late in that season when Edoga returned and reclaimed a starting role. Guyton’s second season began in the starting lineup, but he played 10 games before an ankle injury sidelined him for the remainder of the year.

Dallas has also treated left tackle as a competition rather than a locked-in continuation, with Pro Football Rumors reporting that the Cowboys had Guyton competing with Nathan Thomas for the starting role. That report describes Thomas, a seventh-round pick out of Louisiana, as the primary left-tackle backup in 2025. When Guyton went down, Thomas filled in for the next three games, and Pro Football Rumors says Pro Football Focus ranked Thomas 83rd out of 84 tackles at the position.

As the offseason moves forward, the Cowboys are weighing what they can get from their current roster and how quickly they can restore the offensive line’s ceiling. Pro Football Rumors indicates that the staff could turn to Tyler Smith if the competition does not produce a reliable starting left tackle. The question, in practical terms, is whether Smith can be an immediate stabilizer rather than a short-term fix.

The official Dallas Cowboys team site has framed training camp as the point where answers become more concrete, with the club set to depart for camp in less a month. That timing matters because left-tackle clarity affects everything around it, from who gets reps together to how smoothly protection concepts can be rehearsed and adjusted. For a team that wants its front to be a strength rather than a work-in-progress, summer reps are where the margin is earned or lost.

If Dallas cannot settle on a left tackle early, the ripple effects could show up throughout the offensive line rotation, even when the rest of the group is capable. The Cowboys’ staff will likely prioritize continuity and communication at the position, using camp evaluations to narrow the path to a stable starting lineup.

What to watch next is whether the Cowboys’ internal plans hold up once camp practices begin, and whether any of the competing options can separate through both play and availability. Left tackle is rarely a one-week problem, but it can become one-week certain if a player turns practice into position security. Until then, the Cowboys will keep trying to convert competition into certainty before the regular season forces decisions to stick under pressure.
