Jim Souhan grades the Vikings after their 31-30 loss in Chicago

Coaching: D. Hard to give coaches credit when their blame becomes key talking point.

Offense: C. Better in 2nd half, but zero offensive points until late second quarter is not ideal.

Defense: B. Four turnovers and a touchdown were overshadowed by late breakdowns.

Special teams: C. Locke was effective and Patterson took one back 105 yards, but Hester got loose too often.
