Even though this is the Dallas Cowboys fourth preseason game, it’s their “dress rehearsal” since they still have one more to play after they meet the Raiders on Saturday night. As such, Cowboys fans should get a decent look at the starters in the game, including, apparently, Ezekiel Elliott. Dak Prescott and the rest of the Cowboys should get extended time to build on their stellar performance last week against the Colts. Can Jonathan Cooper put a hammerlock on the starting left guard position Saturday night? A strong performance just might lock it up for Cooper.
