This game will determine whether the Packers will be limited to contending for the NFC North crown and a possible 1st round bye, or whether they will have a shot at home field advantage throughout the playoffs. The Packers currently occupy the 6th playoff spot. However, a Packer win over the Falcons coupled with an Eagle win at Chicago (very possible) would I believe, vault the Packers into the #1 spot overall.
Both of these teams are tougher defensively in the red zone than they are between the 20's. Red zone efficiency may well decide this game.
