6. Seattle Seahawks vs. Arizona Cardinals

This began to be a rivalry last year, when the Cardinals began to show the world that they are a team on the rise. Of course, that does not sit well with the folks in Seattle, who expect the Seahawks to be at the top of the NFC West for some time with the duo of head coach Pete Carroll and quarterback Russell Wilson. Last year, the Seahawks were able to beat the Cardinals twice, mostly because Carson Palmer was out with a torn ACL.

This time around, Palmer is healthy and Arizona has an early two-game lead in the NFC West over the struggling Seahawks. Seattle will have its chance to close the gap with two games remaining against each other, although winning its home date is no guarantee. In 2013, the Cardinals were able to go into CenturyLink Field and win, the only time the champs lost a home game that year.
