Grier entered early and offered a different rhythm than Milton, finishing 1 of 5 for 33 yards across his only series. His role in the backup competition remains open, with coaching staff signaling a true open competition behind Prescott, reinforcing the fantasy implication that clear separation between Milton and Grier could shape Week 1 depth charts.

Grier is the veteran-in-waiting behind Milton, offering a different skill set and a potential No. 2 path if Milton falters. His limited live reps to date leave questions about ceiling, dynamic, and how Dallas would deploy him in relief duty or as a contingency.

Grier is expected to play the majority of the game for Dallas, but his track record is limited. In a preseason setting, he represents upside but with a high variance floor, optimally used in DFS as a speculative, low-cost option with the potential for late scoring if Dallas sustains drives.

Will Grier remains an intriguing prospect within the Cowboys' quarterback lineup. His previous NFL performances have shown flashes of potential, but consistency and adaptation to the team's system will be essential for him to secure a lasting role.

Will Grier is stepping into the backup quarterback position for the Cowboys following Cooper Rush's departure. His performance will be critical in the event of Prescott's injury.
