In week two of the preseason, Seattle (2-0) started a few more players on offense and defense than Dallas (0-2), who again started most of its players on the bench.

The Seattle coaching staff was “really pleased with the overall feeling of the game from start to finish,” as described by head coach Pete Carroll. As the coach put it, “we got the (starters) a little bit of work, you know selective (starters) played on both sides of the ball and got enough to just get them out there.”

Smith’s starting offensive line allowed him two drives, the second of which resulted in a Jason Myers 57-yard field goal. Smith completed five of six passes for 46 yards in his brief appearance.

Lock took over in the second quarter and kept proving he would be a strong option if the Seahawks had to go to their backup. Lock completed 5 of 6 passes for 119 yards and a touchdown, including a 48-yard pass to first-round pick Jaxon Smith-Njigba.

Halftime score: Seattle 17, San Francisco 7. SaRodorick Thompson scored on a 1-yard dash. After absorbing a low hit from Sam Williams that resulted in a roughing penalty, Lock only played in a few of series and looked a touch gimpy.

According to Carroll, the squad intended to give Lock more playing time but remained cautious. According to Lock, he should be alright.

I wanted to demonstrate tonight to not just the coaches but the squad that I will be prepared whenever called upon, Lock said.

Cooper Rush, who entered the game in place of Dak Prescott, passed for 96 yards and a score on 9 of 14 passing to running back Rico Dowdle from 6 yards out in the second quarter. The first time he touched the ball in the third quarter, Deuce Vaughn scampered 14 yards for a score, bringing Dallas within 17-14.

In the last preseason game, Cowboys head coach Mike McCarthy indicated his team will be keeping a careful eye on the rookie running backs.

Because “this young group has a chance to be pretty good,” McCarthy emphasized the need of getting a thorough appraisal of the team this week against the Raiders.

To no avail, Dallas would draw no nearer. Will Grier passed for 136 yards on 13 of 18 passing, but Seattle’s Tre Brown picked him off on the goal line. Brown, who had been out for the most part of the previous two seasons due to serious ailments, saw significant playing time this year. On fourth-and-3 from Seattle’s 28-yard line with about two minutes remaining, Grier was sacked for a loss of 20 yards.

To be very honest, when I threw the ball I expected to score a touchdown. We just could not communicate well with the recipient. “I felt like I played really well,” Grier said.

John Hall, Seattle’s backup wide receiver, blocked a punt by Dallas, resulting in a safety.

Later in the season, on a Thursday night in late November in Texas, the two teams will meet. Pete Carroll, Seattle’s head coach, said it would be an issue to play the Cowboys in the preseason if they were a regular season opponent, but he isn’t worried about it since the regular season matchup won’t be until Week 13.
