QB depth chart: Dak Prescott had his best practice of training camp on Wednesday when he completed all 18 of his passes in team and 7-on-7 drills. He was just as efficient in his opening action of the preseason Saturday. He finished two series, Tony Romo Jerseyscompleting 7 of 8 passes for 106 yards and a touchdown pass of 32 yards to WR Dez Bryant. Dak Prescott JerseysPrescott's only incompletion came on a batted-down pass at the line of scrimmage. He left after 17 plays.

When it was starters vs. starters, the Cowboys looked...: Would outstanding be too strong? Yes, RB Darren McFadden fumbled on the second drive, but the Cowboys faced third down just once on the first two drives and WR Cole Beasley converted that. Dez Bryant JerseysMcFadden ran for 59 yards on nine carries. Ezekiel Elliott JerseysTE Jason Witten had two first-down catches. The defense had two three-and-outs and did not allow a first down in the first quarter. That has to give the Cowboys confidence going into their next preseason game against the Oakland Raiders, when the starters could play into the third quarter.

One reason to be concerned: QB Kellen Moore did himself no favors with a sack-fumble that was returned by former Cowboy Lavar Edwards for a Colts touchdown. That came after an ineffective 8-of-17, 69-yard showing against the Los Angeles Rams in the first preseason game. In six series, Moore completed 10 of 21 passes for 131 yards and directed the Cowboys to one scoring drive. Meanwhile, Jason Witten Jerseysrookie QB Cooper Rush needed just six plays to deliver a touchdown pass on his first series.
