Vikings confident at 4-1, but not comfortable

But here they are at 4-1, tied with Chicago and two games ahead of Green Bay in the NFC North. The victories haven't been flukes, either. Their defense has given up only three touchdowns in the last three games, two of them in the fourth quarter with a healthy lead already established. The offense has been balanced. The special teams have been superb.
