Reality check

Although the Chicago Bears are the defending NFC champions, the 2007 team looks like a shell of the 2006 model. The defense, despite its reputation, has looked susceptible in several games this season, and the offense is still error-prone and erratic.

The Vikings' win at Soldier Field was huge (they hadn't won there since 2000), but how good this team really is will be determined Sunday in Dallas.

There is no question the Cowboys are the class team in the NFC. They are 5-1, boast the No. 2 offense and the No. 11 defense.

This will be the Vikings' toughest challenge both on offense and defense.
