I make this game Vikings -3.5... ASSUMING that we have a full capacity crowd. With the game likely having no or a limited crowd, the Vikings HFA takes a significant hit. I make this game Vikings -2.5, giving us value going through the key number of 3.
I am not a big trends guy, but one trend I think is applicable is divisional dogs in week 1. Teams typically aren't hitting at full stride yet early in the season, and it keeps these games between familiar opponents super close. Divisional dogs since 2014 are 21-5-1 ATS, including 4-1 last season.
I think eventually the friction between Rodgers and the Packers front office hurts this Packers team negatively, but I suspect we see a super motivated Rodgers for his first game since the Packers essentially signaled to Rodgers that they are planning on life without him in 2-3 years. Plus, the Vikings will be breaking in a completely new cornerback group with very little experience.
