The Seahawks fly to Los Angeles Friday ahead of Saturday's game against the Chargers at the StubHub Center, their first road contest of the preseason. And as much as Seahawks coach Pete Carroll wants to see his players perform well on the road, what he really wants to see is for the Seahawks, and young players in particular, to play a cleaner game after committing 12 penalties last week, 10 of which came in the second half when the starters were out of the game.

"We need to clean up all the stuff that happened in the second half," Carroll said. "We had 10 penalties in the second half, we need to get rid of that. That was terrible. The first half was fine and clean and all that, we moved the ball well, did a lot of good things, but that got in the way in the second half. It was all when the young guys were on the field, and they need to be poised and make good decisions and play good clean football."

While Carroll didn't specify exactly how long starters will play, the first-team units generally are on the field a bit longer than in the first preseason game, when almost all the starters on both sides of the ball, aside from a few younger players, came out of the game after one series. With that in mind, here are six things to watch when the Seahawks face the Chargers Saturday night:

1. Can the starting offense build off of a successful debut?

Seattle's starting offense played only one series, but it was as Carroll put it, a "perfect start" for that unit. The Russell Wilson-led offense went 75 yards on 12 plays—seven rushes and five pass attempts—a drive that ended with a Wilson touchdown pass to tight end Nick Vannett.

That's obviously a good way to kick off preseason play, but the goal now for players on that side of the ball is to show they can keep that up, and do so against a talented Chargers defense.

As center Justin Britt put it following last week's game, "We've got to go out there next week and prove that it wasn't a fluke and that this is really us. We've just got to continue to grow, continue to work."

Asked what he's hoping to get out of preseason game No. 2, Wilson said, "I want to see efficiency, obviously, as always. We want to have great up-tempo offense. We want to be able to get in and out of the huddle and execute. They have a good defense. They've got some good rushers and stuff like that. Got some good players, so it will be a good challenge for us and we're excited to go on the road. That's one of the biggest things we want to see, is us go on the road and respond on the road and see how we can do there."

2. With Rashaad Penny out, how does the rest of the running back depth perform?

Rashaad Penny's finger injury only further solidifies Chris Carson's status as the team's starting running back right now, but there's a lot of talented depth at that position beyond Penny and Carson, meaning plenty of players will get their chance to shine and make their case for playing time going forward.

In particular, this is a big opportunity for C.J. Prosise, who missed last week's preseason game with a hip flexor injury. After battling injuries the past two seasons, Prosise is looking to finish the preseason strong and show he can be the player the Seahawks saw glimpses of in 2016.

"Every one of these opportunities are big for the guys, and for C.J., because he missed one, it steps up a little bit," Carroll said. "We'd like to see him play quite a bit in this game."
