ST. LOUIS — Having their starting offensive line together for the first time this season was a boon to the St. Louis Rams' offense, especially their rushing game.

The Rams gained 367 offensive yards, including a season-high 173 rushing yards, in their 31-17 win over the Arizona Cardinals on Sunday.

"We felt real good about it during the week with the way Scott (Wells) had practiced and they way they had been working together with Rob (Turner),'' Rams coach Jeff Fisher said. "Overall, they probably had our best game. Now, we had some issues, which you're going to have against that good defense, but the results and the production from that running game reflects that. They did a pretty good job up front.''

Wells was back at center for the first time since suffering a broken foot in the Rams' season opener.

The Rams' offensive line keyed an 11-play drive in the fourth quarter that chewed almost seven minutes off the clock.

The Rams ran the ball 10 times during the drive, which ended with a 19-yard field goal by Greg Zuerlein that extended their lead to 31-17.

"It is kind of what we talked about not only at halftime, but also at the quarter change,'' Fisher said. "This is how we're going to have to win this game: The offensive line has to take it over. And, they did with some help from 'Jack.' That's how you win games on the road. When you have a lead in the fourth quarter, you have to keep the ball.''

Rams running back Steven Jackson had 24 carries for a season-high 139 yards in the game.

"I think what we saw out of 'Jack' yesterday is what we're going to see the rest of the year,'' Fisher said. "It was a pretty impressive effort yesterday. It was fun to watch from the sideline.''
