710ESPN Seattle audio: Where West stands

The San Francisco 49ers' convincing victory at Green Bay in Week 1 undercut preseason talk about another NFC West team challenging for the division title.

Bob Stelton, Dave Grosby, Dave Wyman and I discussed that and other issues in the NFC West during our weekly Thursday conversation on 710ESPN Seattle. That audio is here.

The offensive line situations outside San Francisco appear concerning.

Two Arizona Cardinals offensive linemen showed up on the "Had a Bad Day" list from Pro Football Focus. The Cardinals had a league-high four players on the 29-player list. Running back Ryan Williams was one of them, but his struggles were tied directly to the problems his line had against Seattle.

Arizona had 20 carries for 43 yards, gaining 15 of those yards on a reverse by receiver Andre Roberts.

"I wish I could tell you, 'OK, you can wave the magic dust and we’ll run the football well,' " coach Ken Whisenhunt told reporters after practice Wednesday. "We are going to work at it, and once again, we did well in preseason, but that doesn’t mean anything. Some weeks we are going to be able to run it better. Some weeks we are going to have to throw it."

The Cardinals' Week 2 opponent, New England, held Tennessee to 1.3 yards per rush on 16 carries, with one rushing first down. Only the Tampa Bay Buccaneers allowed fewer yards per carry last week.

The Patriots had seven or fewer defenders in the box for all but one of the Titans' 16 carries, according to ESPN Stats & Information. That is probably at least partly because New England jumped to a big lead, forcing Tennessee into passing situations. The Titans attempted 43 passes, the seventh-highest total in Week 1. The Patriots won, 34-13.

Titans quarterback Jake Locker gained 11 of the Titans' 20 yards rushing. Chris Johnson's longest run covered five yards.
