In their first preseason game against the Seattle Seahawks, the Dallas Cowboys evaluated their backup offensive line players. Key performers included T.J. Bass, who started at center and received a grade of B+ for his solid play and consistency. Nate Thomas started at left tackle and graded C+, showing potential but needing improvement. Nick Leverett also played at center, earning a C+ for his steady yet unspectacular performance. Trevor Keegan, starting at left guard, received a C grade for decent blocking but needed to improve his footwork. With the starters not participating, the team focused on solidifying depth ahead of the regular season.
