For the first time in a while, the Cowboys won’t be entering the preseason with a veteran presence at backup quarterback. There’s only three years of NFL experience between all four quarterbacks with Dak Prescott entering his third-year. The preseason isn’t for guys like Dak, who have established their current positioning on the roster. The preseason is for guys like Cooper Rush and Mike White, who will be auditioning for Dak’s primary backup spot.
Cooper Rush impressed coaches enough in his rookie preseason that the Cowboys decided to give him the QB2 duties for the 2017 season.
