The headline takeaway from Brian Schottenheimer's Thursday presser isn't that Tyler Guyton is back from his elbow injury.
It's that Guyton isn't the starting left tackle.
“I have not said that Tyler Guyton is a starting left tackle of this football team,” Schottenheimer said. That's not a slip. It's a deliberate hedge from the Cowboys' offensive coordinator, who had every chance to end the "competition" narrative and chose not to. The real message is in the rest of the statement: “Nate Thomas needs to prepare and play a little bit better and more of a consistent starter capability to earn the right.” Thomas isn't simply being groomed; he's being challenged to take the job. Meanwhile, Guyton, the 2024 first-round pick now entering his third NFL year, still hasn't been handed the blind-side protection duties for the team's $50-million-per-year quarterback.
Despite this, the betting market hasn't yet factored in the uncertainty at left tackle. The Cowboys are +2200 on FanDuel and BetOnline to win the Super Bowl—implying the line is expected to be competent enough to support a championship run. Schottenheimer’s comments throw that assumption into question at the most critical position on the offensive line.
No Clear Competition—or Is There?
Schottenheimer initially said, “There is no competition at left tap,” referring to left tackle. However, he then clarified that Nate Thomas received reps “because of Guyton’s elbow.” Yet, the coach also emphasized Thomas needs to “play a little bit better and more of a consistent starter capability to earn the right to compete.” This is contradictory. If there truly is no competition, why is Thomas being evaluated on consistent starter capability?
The reality is that Guyton’s elbow injury is more than a brief issue. Schottenheimer confirmed Guyton is “back with the elbow,” and Thomas's meaningful first-team reps during camp are no experiment—they represent a real evaluation. Thomas, the 2024 seventh-round pick (No. 233 overall), has never started an NFL game before, but he’s gaining significant reps with the starters. This indicates the Cowboys are not fully confident Guyton is the answer at left tackle right now.
From a fantasy and betting perspective, this is significant. Dak Prescott's sack prop bets, for instance, become riskier depending on who controls the blind side. Guyton struggled more with pressure than expected in his first two seasons, while Thomas is unproven but praised internally for his anchoring ability. The distribution of snaps between Guyton and Thomas in Week 1 will be a crucial signal for the Cowboys’ offensive ceiling. Currently, the prevailing uncertainty suggests a conservative bet on Dallas’s early scoring output.
Physicality: The Key to the Left Tackle Battle
Schottenheimer spent notable time emphasizing the physicality of their padded practices: "We're striking. They're picking up blitzes. They're blocking." He praised the players for "destroying blocks" and expressed pride in the offensive line's playing style. This theme strongly implies a direct message to Thomas, whose biggest challenge has been maintaining consistent physical performance. On some plays, Thomas can neutralize pass rushers effectively; on others, he has struggled to hold the edge, occasionally allowing defenders back into the pocket.
This inconsistency informs how the Cowboys' rushing attack might unfold. Javonte Williams, last season’s lead back, ran for 1,201 yards on a solid 4.8 yards-per-carry average, helped by a line able to create movement and open lanes. If Thomas takes most reps at left tackle, opposing defenses are likely to test his ability with stunts and pressure schemes designed to exploit any weaknesses. This situation should temper expectations for Williams’s rushing yardage prop in early games, even though he remains the team's primary ball carrier.
Pads On, Battle On
Schottenheimer emphasized the importance of physical, padded practices: “Today’s another really good padded practice. There’ll be some nine-on-seven.” Offensive line battles come down to performance when the pads are on, and this is when the coaches truly see who can handle NFL power and speed. Thomas’s analytical film study and strength advantage play into his favor here, while Guyton’s upside lies in his athleticism and potential.
These comments suggest the coaches are closely monitoring Thomas’s ability to translate practice reps to true game readiness under full contact conditions. Watching the next few padded practices will be crucial to understanding whether Thomas continues receiving first-team snaps or if Guyton reclaims the role outright.
Market Implications
The Cowboys’ Week 1 offensive totals and Prescott’s sack props are being priced under the assumption of a competent offensive line. Schottenheimer’s refusal to name Guyton as the starter signals that this line isn’t settled. Consequently, bettors and fantasy players should be cautious about taking overs on Dallas's early-season scoring or rushing props until the left tackle situation is clarified.
In particular, Prescott’s sack prop offers a clear edge. If Thomas wins the starting job, sack risk could increase given his relative inexperience. If Guyton starts consistently, pressure might be more contained, but his prior struggles temper that confidence. Until then, this uncertainty constitutes a critical factor in evaluating the Cowboys' offensive outlook entering the 2026 season.
Schottenheimer’s deliberate vagueness about the left tackle position is the headline. For now, that uncertainty should lead bettors and analysts to adopt a cautious stance on Dallas’s offensive production in the early games of the season.
