Chicago won pretty handily last time around so I think they will win again, but even they can't stop AP who already ripped them for 108 yards and 6 receptions last time they met.
Percy Harvin being out certainly does not make it any easier on the Vikings though. Bears should take it.
EDIT: Vikings are tearing them up early.
