That's because the public stills sees the Packers as the Packers of old and Vegas knows that. Can't say the without a doubt they will lose Sunday, but I think their season ends this week, IMHO.
The only issue I would advise caution on is picking an experienced team over a rookie playoff team....err,...vice versa.....
teams like the steelers , the hags and the Pack just know how to win in the playoffs...from the head coach down to the ballboy they know how to prepare...while teams like cincy and the vikes just do not have that experience.....I would only pick the "new" playoff contender if they are overwhelmingly better across the board....it would also seem that certain teams "nostalgia" factor gets them an extra benefit of the doubt from most officiating crews.
