First off let me say that I think the Cowboys win by two scores in this one, but I do think it's a massive mistake to just assume the Cowboys will put up 40+ and this one ends up being a walk in the park. The Cowboys are by far the more complete and talented team, however the strength of the Packers align well with the Cowboys weaknesses.
Aaron Jones is the type of back to give the Cowboys run defense fits and if he does they'll grind the clock and keep Dak and this offense on the sidelines. The Packers defense has some holes that the Cowboys should be able to exploit, however they're still giving up just 20.6 PPG this year, the Cowboys are at 18.5, both top 10 in football. That secondary is pretty suspect, however they have two excellent edge players in Gary/Smith who are both excellent run and pass defenders. Kenny Clark up the middle isnt a joke either. If this oline isn't 100% healthy this week I don't like that matchup of their Dline vs our Oline.
I think this game comes down to the run game for both sides. If the Cowboys can keep Jones/Dillon somewhat in check and avoid the constant 3rd and short situations this game could be a blowout in the Cowboys favor. If they are giving up 4-5 yards per play on the ground Jordan Love has shown that he is plenty good enough to carve up a defense, and they are three deep at receiver. I'm really not worried about the chunk plays, I hope that's the game GB tries to play.
On the flip side, Dallas needs to be able to run the ball. The packers are more than capable of getting to the QB on those obvious passing downs. While that secondary isn't very good they do have the guys up front.
IMO it just feels like a classic case of if the Cowboys can get an early lead they should cruise to victory as Jordan Love is forced to try and win it with his arm in a shootout. If GB can come out and punch them in the mouth early it could be a dog fight all game.
