Viking had a terrible year this last year so I am going to say No to them. Hell even Viking fans here in MN aren't too thrilled with it.
NFC: Packers, I'm going to go ahead and say they will come off to another super bowl or choke at the playoffs.
AFC: Chargers for the reason titan said, If they can start their season off with a bang and keep it going for once. Usually they do good, I'm sure they will come around to reclaim their Division title and Hopefully not Choke in the playoffs.
