A year ago, the Vikings led the NFL in sacks with 48. Through six games this season, the Vikings have only six sacks, which is tied for 30th. Only Tampa Bay with five has collected fewer sacks.

The Vikings did not sack Packers quarterback Aaron Rodgers in a 28-24 loss on Sunday night after sacking him 14 times in two meetings combined last season.

The Vikings continue to point to the way teams employ different protection schemes and quick-hitting passes to offset the pass rush. Kevin Seifert of ESPN.com had an interesting stat in his postgame report via the network's stats department.

According to ESPN Stats & Information, the Vikings rushed four or fewer players on 27 of Rodgers 37 dropbacks.

"At times they weren't even rushing," Rodgers told Seifert. "They were more content with kind of standing at the line of scrimmage and really jumping. When you can slow down two great rushers like that, that's a good thing for us."

Jared Allen intercepted a pass at the line and had another pass breakup while Kevin Williams batted one pass down.

"You say we weren't getting a lot of pass rush but there wasn't a lot of deep dropbacks," Williams said. "I don't think he held the ball more than three seconds maybe five times. He was getting the ball out. We were trying to push as much as we could and then get our hands up."

The Vikings scheme relies on their front four to be able to get pressure on the quarterback without needing to blitz as often. That's especially important with their issues at cornerback.

Rookie Chris Cook came back from a knee injury Sunday and struggled before being pulled from the game. Coach Brad Childress said he was pleased with the play of Frank Walker in relief, but Walker was not even playing football until the Vikings signed him as a free agent two weeks ago.

Williams again pointed to teams using a quick passing attack to neutralize their pass rush and put pressure on their secondary.

"Teams are going [to do that] until we fix the problem," he said. "You've just got to get your hands up and get as much push as you can and just tackle. If he makes a three-yard route, we've got to tackle him for a three-yard route and not let it turn into a seven or eight or even 30-yard gain."

Williams was asked if the defense should blitz more to help get pressure on the quarterback.

"We could but I don't think it would help," he said. "With the ball coming out, that's just going to get eight guys in the backfield and less guys trying to get him down. Me personally, I wouldn't. But I'm not the defensive coordinator."
