The Vikings, 16th in the NFL in passing defense, will need another great performance from Jared Allen on Monday night against the Bears to make sure that quarterback Jay Cutler, who has thrown 25 interceptions this season, doesn't have a game like Matt Moore had for the Panthers last week.
Allen has 13 1/2 sacks this season, second in the league to Denver's Elvis Dumervil, who has 15. But Allen has only one sack over the past three games. However, the defensive end has 6 1/2 sacks in three games against the Bears since joining the Vikings, including two in Week 12 at the Metrodome, when the Vikings won 36-10.
Chris Williams took over at left tackle for Chicago after veteran Orlando Pace got injured in that game at the Metrodome. Williams, a 2008 first-round draft pick by the Bears, is expected to make his fourth start there Monday.
"I find a majority of the time it is just a mind state [playing vs. younger players]," Allen told the Chicago Tribune. "The bottom line is you just have to take it to them. You have to try to get a young guy out of his comfort zone and force him into situations he hasn't experienced yet."
The Panthers found a way to keep Allen away from Moore last week, and the Cardinals also had good luck blocking him from Kurt Warner.
Quick passes have caused the Vikings defense a lot of problems in the losses at both Arizona and Carolina. Defensive coordinator Leslie Frazier was asked how the Vikings can do a better job defensing against them.
"We are going to see that [the short passes]," Frazier said. "We've been seeing them for the past four or five weeks. A lot of three-step drops, a lot of maximum protection. So that is not going to change.
"What has to happen when people go to the three step -- and it's been in games we've won as well -- you've got to tackle and limit the yards after the catch. You limit yards after the catch and put them in long-yardage situations by not allowing them to run the football on early downs, and you will have a chance."
