Power Rankings: No. 9 Arizona Cardinals

A weekly examination of the Cardinals' ESPN.com Power Ranking:

Preseason: 26 | Last Week: 13 | ESPN.com Power Ranking since 2002

Welcome to the top 10. Arizona officially staked its claim this season as an upper-echelon team by cracking the top third of ESPN.com's Power Rankings. And with how they played against the Colts, it is deserved. Even during the game, some Colts fans began complaining that Arizona was beating up on them without Reggie Wayne and Vick Ballard. It doesn't matter who the Colts did or didn't have, the way Arizona played on offense (Wayne and Ballard don’t play defense) said more about this team than anything else.

Say it however you want: It clicked. The light bulb went on. It's working. It all means the same thing. Arizona's offense is finally on track after months of learning the intricacies and nuances. When paired with one of the best defenses in the league, this is the result. It's not the final product, coach Bruce Arians insists, and he doesn't think teams fear the Cardinals just yet, but this offense has too many pieces to stop. Its rotation is deep at running back, wide receiver and tight end, always bringing in fresh legs. There's plenty of season left, but if the offense keeps gaining steam, this is a team to watch out for come January.
