Saints have had the easiest schedule this season so far
That is based on overall DVOA. I like checking out DVOA for specific thing sometimes but their overall team numbers can be pretty weird.
For example, we are ranked 8th in overall DVOA. They have Denver, Seattle and Chicago ahead of us. I think its the way they combine offensive, defensive and special teams DVOA together to get a team value.
If you build a SoS with that list it's going to be pretty wonky.
