Cowboys Prefer To Keep Tyler Smith At LG; LT Competition Expected

The Cowboys are returning all five of their starting offensive lineman from the 2025 season, but left tackle Tyler Guyton is not assured to keep his job after a disappointing start to his career.

Guyton, 24, played right tackle at Oklahoma before he was drafted by the Cowboys in the first round (No. 29 overall) of the 2024 draft. He was asked to flip to the left side in Dallas, a switch that clearly did not take right away. He allowed six sacks as a rookie with an overall grade of just 50.4, per Pro Football Focus (subscription required), while also committing 18 penalties. There were some improvements in 2025, though he only started 10 games due to a season-ending ankle injury. Guyton surrendered two sacks, improved his grade to 57.5, and reduced his penalty count to seven. Still, that is not the level of play expected for a first-round pick or accepted for the protector of the blind side of the league’s most expensive quarterback.

As a result, the Cowboys are poised to hold a competition for the starting left tackle job this summer, according to The Athletic’s Jon Machota. 2024 seventh-round pick Nathan Thomas and Drew Shelton, a fourth-rounder in this year’s draft, will also vie for the job.

Thomas, 24, took over for Guyton after he landed on injured reserve, but was benched after allowing 23 pressures and three sacks with a 93.5 pass blocking efficiency, per PFF. 2022 first-rounder Tyler Smith moved over from left guard to close out the season and allowed just five pressures and one sacks across three games.

Dallas intends to keep Smith at guard, where he has earned three straight Pro Bowl nods after an uneven rookie year at left tackle, his college position. This would maintain a solid interior trio of Smith, center Cooper Beebe, and right guard Tyler Booker (with Terence Steele set to return at right tackle).

Shelton, 22, started at left tackle for the Nittany Lions for most of the last four years with some split duties on the right side in 2023. His grades steadily improved throughout his college career, up to 70.6 as a senior in 2025, when he allowed just one sack and zero quarterback hits. He is a solid athlete, but his 33.4-inch arms are below NFL standards for the position. Pre-draft evaluations pegged him for a swing tackle role early in his career with potential to grow into a starter, but he may have a shot at the job right away.

Cowboys head coach Brian Schottenheimer praised Shelton’s “smooth footwork” and athleticism at the team’s rookie minicamp and confirmed that he would be competing with Guyton and Thomas this summer.

“We just like the traits, and we bet on a guy that’s played, I think, 34 starts,” Schottenheimer said (via Machota). “We think we can get him in here to compete with some of the guys we got.”

A relatively unheralded fourth-round pick seems like a long shot to start at left tackle as a rookie, but the team’s other options do not inspire much confidence. And if none of the three can emerge as a starting-caliber player, Dallas could still pivot back to Smith and put a different player at left guard, though again, that is a situation they would prefer to avoid.
