The Viking are playing well. I don't think they are elite yet, but they are very good. The Bills will be a good benchmark to see where they are. I'm not picking the Vikings to win at Buffalo, but you never know.
I still think the Vikings have not yet reached their ceiling. The offense is still figuring things out. The Defense is much better than last year. Signing Zadarius was a huge move that is paying off.
Agreed, the Bills game will be a good benchmark to see how they have improved since the Eagles beat down.
