Prediction:
Green Bay Packers 27
Seattle Seahawks 20
FINAL
I like this score and thought of something along those lines the past few days.
It's unrealistic in my opinion to expect the Packers to go into Seattle and dismantle them the way they did at Lambeau in 2016. The Seahawks have sort of come back to life, and it's difficult to win there. They have lost two games at home this year, but to legitimate competition (Rams, Chargers).
Also, the Seahawks have yet to lose a game by more than one score this season. It would take a remarkable effort from the Packers offense to change that tonight.
Additionally, since the start of the 2012 season, the Seahawks have only lost 3 (!!!) regular season games by double digits. The good news? One of the was a 42-7 drumming last year at the hands of the Rams, and the other two have been courtesy of the Green Bay Packers (27-17 in 2015, 38-10 in 2016).
Though both of those games were at Lambeau, I think the Packers have sort of figured out how to play against the Seahawks and I think there's been a little extra incentive against them since the 2014 NFCCG debacle.
So that being said, I'm going to go with 27-23 Packers.
