Tyler Guyton has totaled 21 starts at left tackle early in his career. It is not certain he will remain atop the depth chart heading into his third Cowboys season, however.
Head coach Brian Schottenheimer said on Thursday (via ESPN’s Todd Archer) Guyton and Nate Thomas will compete for the starting gig at left tackle this offseason. Spring workouts are underway already, but the evaluation for offensive and defensive linemen in particular will of course truly begin during padded practices in training camp. That period will be critical for Guyton.
Schottenheimer offered praise for the 2024 first-rounder based on how things have gone so far in offseason work. Guyton will nevertheless need to earn his first-team position this summer. Penalties and sacks allowed were issues during his rookie campaign. While the Oklahoma product managed to improve in both areas in 2025, his PFF evaluation for last year left plenty to be desired.
Guyton will enter training camp as the favorite to retain starting duties at left tackle, Jon Machota of The Athletic writes. 2026 will mark his age-25 season, and improved play would be critical in stabilizing the blindside for Dallas now and in the future. It would also make the Cowboys’ fifth-round option decision easier in Guyton’s case, of course; a call on that front will need to be made next spring.
Thomas was also taken in the 2024 draft, joining Dallas as a seventh-rounder. After not playing during his rookie campaign, Thomas appeared in all 17 games last season (totaling four starts). The Louisiana alum drew poor PFF grades for his pass protection in particular, so expectations would be tempered in the event he were to begin 2026 on the blindside. Machota writes fourth-round rookie Drew Shelton could also see looks at left tackle if needed.
A contingency could be for the Cowboys to move Pro Bowl guard Tyler Smith to left tackle. As Smith recently told Schottenheimer (via the team’s website), though, his preference would be to remain on the inside on a permanent basis. Machota confirms Smith playing at tackle is a scenario neither team nor player would prefer. As a result, the performances of Guyton and Thomas will be worth monitoring closely over the course of the summer.
