The 49ers and Seahawkspossess two of the league's strongest rosters, but Arians oversees a Cardinals team with sneaky talent. Two gaping voids -- at quarterback and along the offensive line -- were addressed in the offseason, and Arizona has the making of a nasty young secondary led by Patrick Peterson.
It wasn't long ago that San Francisco and Seattle were adrift in a division ripe for taunting. Jim Harbaugh and Pete Carroll revived those respective franchises, and Jeff Fisher is doing the same with the St. Louis Rams. It's easy to treat the Cardinals as a footnote, but Arians won't let his players think that way.
