A weekly look at what the Vikings must fix:

Minnesota allowed six sacks Sunday afternoon in a game where the New England Patriots moved Chandler Jones from a 3-4 outside linebacker position to a 4-3 defensive end spot, putting him in position to work against left tackle Matt Kalil for a large portion of the game. Kalil gave up two sacks -- one to Jones on a speed rush, and one to linebacker Dont'a Hightower on a blitz.

Even though the Vikings will face a New Orleans Saints team that has just two sacks this season, they'll be returning to a dome, where noise figures to be a factor in the Saints' home opener. If the Vikings want to avoid a second consecutive loss and get their offense in order after a 30-7 defeat on Sunday, they'll have to do a better job protecting Matt Cassel.

One thing to keep in mind is how much more help the Vikings were able to give Kalil in Week 1 than they did in Week 2 through the use of either tight end Rhett Ellison or Kyle Rudolph in a blocking role. Part of that, of course, was due to the score of the game against the Patriots and the fact the Vikings had to spend much more time in three-receiver sets as they tried to rally than they did in Week 1. But if the Vikings find themselves in that situation again, they have to be able to trust their left tackle to handle his man. It's worth noting, too, that Kalil and Charlie Johnson gave up a combined three quarterback hits and six hurries, according to ProFootballFocus.com.

With Adrian Peterson back this week, the Saints undoubtedly will have more to think about in stopping the Vikings' offense, but if the pass protection isn't better, there's only so much even Peterson can alleviate.
