After Sam Bradford's left knee injury, the Vikings have used Case Keenum and Bradford as their starting quarterbacks. But this really has been, and most likely will continue to be, Keenum's season in that role. He has taken 72.4 percent of the snaps, while Bradford has taken only 27.6 percent.
This week brings another huge challenge as the Vikings have a chance to take over the NFC North lead if they can beat the Packers at U.S. Bank Stadium on Sunday.
Keenum came in for a clearly hobbling Bradford against the Bears last Sunday and completed 17 of 21 passes for 140 yards and a score in the Vikings' 20-17 victory in Chicago. He said that with each snap, he gets more comfortable with the offense and his teammates.
"That's what experience brings, and I think experience is priceless," Keenum said. "Experience within the offense that you're running with the guys you're running with.
"We have some good experience, good things that we've put on tape. We have a lot of things to work on, too. We have to go to work this week and get better."
When asked to explain how his comfort grows each week, Keenum said it's in the little parts of the game.
"I go out every day and work on something different," he said. "Sometimes I work on the same thing. I'm always trying to perfect my craft, pursuing excellence rather than perfection, that's a phrase I like to use rather than being a perfectionist."
After starting in Weeks 2-4, Keenum replaced Bradford late in the first half against the Bears. He said the coaching staff makes sure all the quarterbacks are on the same page so they are ready for any game situation.
