I suspect you are right, but I am a native Cheesehead (and primarily a Bears fan). I am hoping for GB vs. NE in the SB.
The home teams usually have the advantage. So that favors both Atlanta and New England.
Atlanta has the following advantages too.
1) Less Injuries
2) The number 1 offense in the NFL. Matt Ryan has all types of weapon both air and ground.
3) They already beat Green Bay earlier this year.
4) This is the very last NFL game in the Georgia Dome. The Falcons want to end it with a win.
