The Dallas Cowboys are facing a crucial decision regarding their left tackle position as they prepare for the upcoming season. Head coach Brian Schottenheimer has confirmed a competition between Tyler Guyton and Nate Thomas. There are calls for rookie Drew Shelton to be considered as well. With high expectations for the season, the Cowboys' explosive offense could be jeopardized if Dak Prescott is pressured from his blindside. A potential solution could be signing free agent Taylor Decker, who, despite a less-than-stellar performance in 2025, offers a solid pass protection grade of 69.5. In comparison, Guyton and Thomas have struggled in pass protection, with Guyton allowing 31 pressures and two sacks in 418 snaps and Thomas giving up three sacks in just 219 snaps. While Decker may not be a long-term solution, he could provide the necessary stability while the team develops Shelton. Additionally, competition could enhance Guyton's performance, especially with mentorship from veteran Tyron Smith. The Cowboys need to solidify this position to ensure a successful season.
