RENTON, Wash. -- The Seattle Seahawks believe the current configuration along their unsettled offensive line could very well be the one they take into the regular season. But with competitions still on at three of the five spots and with the team still looking at veterans on the free-agent market, coach Pete Carroll isn't quite ready to make a final decision.

And so the week began with Justin Britt still atop the depth chart at left guard, Drew Nowak at center and Garry Gilliam at right tackle -- for now, at least.

"They've got a chance now," Carroll said when asked if the current group will be the one who starts in Week 1. "...We'll see if they can hold it together and hold off the other guys that are battling with them, but we feel good enough about it. We like the way that they mix together and they have a real chance, so we'll keep that intact again this week and take it one week at a time."

The Seahawks had already been rotating players at center and left guard when they shuffled things up even more last week, moving Britt from right tackle and replacing him with Gilliam. That came after an unimpressive performance from the previous group in the Seahawks' preseason opener.

The new group improved considerably in pass protection Friday night against Kansas City, not allowing a sack during the two quarters in which the starters played. But Seattle still failed to score an offensive touchdown and ran for only 78 yards in a 14-13 loss.

Carroll, looking beyond the final numbers, liked what he saw.

"I was really happy to see the line play together and have success, communicate well," he said. "Drew had a nice first start. He's in the middle of it all. Justin Britt looked really comfortable at left guard, played really solid football. He filled up the space so nice. Garry, who had a great matchup with Justin Houston, fared pretty well over there. It was a really good first showing by the fellas."

Along with sticking with the current group and continuing to mix and match with backups, another option for the Seahawks is to fill one of their unsettled spots with a veteran free agent.

The team met with left guard Evan Mathis over the weekend, but he left Seattle without signing a contract. Carroll said the meeting went "very well" but that "there's a lot of issues that we have to take care of to get that in order." Money would be one of them, as Seattle might not have the cap space to afford Mathis, a two-time Pro Bowler who was reportedly seeking a raise from the $5.5 million he was set to make in 2015 before his release from Philadelphia.

The team was also scheduled to meet with center Samson Satele on Monday, according to ESPN's Adam Caplan.

"We're going to keep competing to see who else is there and available as we try to make our choices," Carroll said. "Really, we're going one step at a time so you'll see some guys' names come up again today. We're continuing to look. We want to know who's available."
