I think the relatively low spread is a recognition of the fact that the Saints haven't actually been home since August at this point, along with much of the coaching staff going into COVID protocol during the same week a number of key starters were nicked up. That the Saints are still favored on the road this week is indicative of Vegas' opinion of the organization's health and the team's depth. One wonders what the spread would have been had the week one results been the same, but without the hurricane and COVID issues for New Orleans and with both teams at full strength.
