Falcons will try to win this game to rest players next week. Detroit is playing for what? Falcons with better offense, better defense and better coaches. I'm not even sure that Lions have any individual player who is better than any individual player of Falcons in the same position.
As far as the total it's a mystery to me. Only way it stays under is if the Lions don't score enough. The Falcons will give you your typical 28-31 points.
