A season can turn sour quickly in the NFL. Just look at the Cardinals and Bengals.

Remember when Arizona was sitting pretty at 4-0? Or when Cincinnati jumped to an impressive 3-1 start? Now both teams are in the throes of three-game losing streaks.

Not that they're the only ones struggling. The Chiefs and Jaguars also have lost three straight, while the Panthers own the league's longest losing streak at four games (costing GM Marty Hurney his job). And let's not forget about the Chargers, who followed a 3-1 start with back-to-back second-half collapses.

Do our voters (ESPN.com's John Clayton, ESPN.com's Ashley Fox, NFC East blogger Dan Graziano, AFC North blogger Jamison Hensley and NFC West blogger Mike Sando) view any of these teams in a positive light? Not really. Arizona and San Diego lead the group at No. 14 and No. 17, respectively, hardly ringing endorsements. (The Cards were No. 5 three weeks ago.) None of the others rank above No. 22 (Cincinnati).

But we won't pile on. No one is out of it yet, and there's plenty of time to reverse fortunes. The Chargers, despite their recent woes, remain a viable threat to win the AFC West. The Cards are only a game out of first place in the NFC West.

Will someone's turnaround begin in Week 8? You never know. As we've seen already, things can change quickly.
