Dak Prescott will only go as far as his left tackle situation allows

Dak Prescott’s 2026 outlook is portrayed as dependent on how Dallas resolves its left tackle situation to protect his blind side. The Dallas Cowboys return all 11 offensive starters, including star receiver CeeDee Lamb, running back Javonte Williams, and an interior line led by Tyler Smith, Cooper Beebe, and second-year guard Tyler Booker, under head coach Brian Schottenheimer and offensive line coach Klayton Adams. However, training camp beginning in California later this month still has not identified a firm left tackle, leaving a two-man competition between former 2024 first-round pick Tyler Guyton and seventh-round developmental tackle Nate Thomas. The article notes Guyton has 21 career starts but struggled in 2025, giving up 31 pressures and six hits in 648 snaps and suffering injuries including a knee issue and a season-ending high ankle sprain. It cites Sports Illustrated’s Albert Breer saying the left tackle spot could make or break the season, especially with a major Week 1 ahead.
