The key for the Vikings defense...

Kenechi Udeze isn't getting it done, and Darrion Scott is more of a run stopper. So the Vikings need someone to fill the void left by Erasmus James, who suffered a season-ending knee injury early in the year.
So that key is rookie Ray Edwards, who had sacks in back-to-back games earlier. But Edwards hasn't had a sack since Oct. 8, and he's hardly made an impact during that time. And when he was expected to start against the Green Bay Packers, Edwards blew his chance with a minor off-the-field misstep.
The college football season is wrapping up, but Edwards insists that he is fine.
"I'm just not getting there right now," he said. "But it's not frustrating. You got to keep working. This is the NFL. Guys are good. They do study tape. I just need to get a good counter to my original moves."
Vikings coach Brad Childress said Edwards has been playing fine, despite the lack of production.
"He's still putting a lot of good rushes on," Childress said. "He's done well on the snaps he's played and I know, again, where you end up heading is saying the litmus is sacks. He's played good. He's played solid defense and done what he's supposed to do."
