In my opinion there are a couple factors in the game.

Patriots:
-establish running game with Fred Taylor/Lawrence Maroney
-Will injured players play (Wes Welker, Jerod Mayo, Brandon Merriweather) major factor players.

Atlanta:
-Tony gonzales has to be able to create space and get catches (NE has averaged 3 catches total for TE per game with averaging 24 yards per game)
-Need to be able to shut down Randy Moss
-Michael Turner needs to be able to rush 80+ yards

but i believe new england will win this game.
Final score 24-17 New england
