The Vikings say they are tired about talking about Week 1 woes, especially the coaches. Offensive coordinator Norv Turner wasn't interested Thursday in addressing why the offense stalled out or how little he used Adrian Peterson in his first game in nearly a year.

"I'm not going to talk about last week," Turner said. "We're trying to get ready and we're going to put a game plan together to give Adrian the best chance to be successful. We're trying to put a game plan together every week to give all our guys a chance to contribute. We really want to be a balanced team and be able to do the things the defense makes available.

"Our focus has been on Detroit. There are some things we want to do better in a lot of different areas, but I don't think Adrian was too quick."

Peterson had 10 carries for 31 yards. The Vikings offense totaled only 248 yards, going 1-for-9 on third downs and 0-for-2 on fourth down in a 20-3 loss to the 49ers.

Turner admitted that the game started badly. Quarterback Teddy Bridgewater threw three consecutive incompletions passes in the Vikings' first drive to squander great field position.

"It's not going to go the way you want every week," Turner said. "Teddy missed some throws early that he normally makes. We had a lot of unforced errors where we created problems for ourselves. ... We have to eliminate unforced errors, we gotta keep people from coming free at the quarterback. It's hard to play when you have people running free at you. I think that will help a great deal.

"We're looking at the things we have to do and the things we do best to give us a chance to beat Detroit. Games come up different and we all know Adrian is a big part of what we do and we want him to be able to have an impact on the game."

Defensive Coordinator George Edwards liked hearing that his veteran players are taking Sunday's poor effort seriously.

"Everybody takes it personal when you put the time in to go prepare for a game, but you also realize that's one game. That's one of 16 games. You've got to concentrate and focus on what we're getting better at today. That's the only way we're going to get better, so we're trying get better today in our preparation for Detroit."

Special teams coordinator Mike Priefer remains confident in his kicker, Blair Walsh, despite another missed field goal opportunity on the Vikings first drive of the season.

"It was just a confidence thing, he's just got to go out there and swing his leg through and get his confidence back," Priefer said. "We sent him down to TCF [Bank Stadium] yesterday and they filmed it, he had a great workout down there. He will be fine."
