I essentially have 3/4 of a season's bankroll riding on this game. I started placing the wagers back in July when the Saints were +1.5 and I had identified it as an insane value. It's obviously emerged as the most mobile line of Week 1 as the hype train for New Orleans built up (Cooks, Byrd, Saints' rushing attack, etc.) and as the Falcons suffered two key injuries (Weatherspoon and Baker) and Mike Smith was revealed as an uninspiring beta male on "Hard Knocks".
Meanwhile, Sean Payton is alpha as frick and makes his guys want to run through a brick wall.
I will flat out state that there is no way Atlanta wins this game unless they are +2 or better on turnover margin. It could happen as Brees has laid some eggs in surprising spots through his career... but it only happens once or twice a season and has never occurred in Week 1. Payton seems absolutely committed to sticking with his deep stable of RB's this season and so I'd be shocked if he falls into an Andy Reid-esque pass happy attack that sometimes hurts the Saints.
I don't have a ton of new insight from what you can now find with a random google search, and I've already posted my thoughts on this game (search my post history if interested) in relatively good detail.
Alpha as hell.
