Just going by comparrison:
GB dominated the Colt's two weeks ago at home en every facet of the game.
Tenn was fortunate to win the game imo last week. Just a bad call when Dungy went for it on 4th and 1 at midfield. That changed everything. ANd if you rememeber, every Tenn fumble or deflected pass or bounce went their way. Even though the final score was 10 points that game was competitive.
I just think Packer run D much stronger than the Colt's plus their running game much stronger than the Colt's. So I think they have a shot in this one.
