Power Rankings revisited: Week 5

A weekly review of how teams performed in relation to last week's Power Rankings:

The Arizona Cardinals were no match for New Orleans in the playoffs last season when Kurt Warner was still playing.

They handled the defending Super Bowl champs Sunday, winning 30-20, with rookie Max Hall making his first NFL start and Warner commentating from the Fox broadcast booth.

It's been that kind of season in the NFL.

No teams remain unbeaten after Kansas City lost 19-9 despite holding Peyton Manning without a touchdown pass. The previously winless Detroit Lions put up 44 points, including 30 on offense, against a St. Louis team that hadn't allowed more than 17 points in a game this season. San Diego lost to Oakland despite finishing with huge advantages in first downs (29-14) and total yards (431-173). San Francisco fell to 0-5 after entering the 2010 season as the NFC West favorite.

Two of the three highest-ranked teams in the most recent ESPN.com NFL Power Rankings lost Sunday (top-ranked Pittsburgh had a bye).

The chart shows how ESPN.com's panelists voted in the Power Rankings last week. Red lettering highlights teams that lost in Week 5. The new rankings appear here Tuesday.

The reckoning: Seven games featured lower-ranked teams beating higher-ranked teams:

  • (25) Arizona 30, (2) New Orleans 20: Reggie Bush appears more valuable with every game he misses. The Saints weren't putting up many points when the running back was available, however.

  • (16) Washington 16, (3) Green Bay 13: I'll be moving the Redskins up quite a bit in the next rankings. Their 30-16 defeat at St. Louis looks more like an aberration.

  • (20) New York Giants 34, (7) Houston 10: Texans are 1-2 against the NFC East and that counts a narrow victory over the Redskins.

  • (29) Oakland 35, (12) San Diego 27: A 400-yard passer and 200-yard receiver could not beat the team with Jason Campbell and Bruce Gradkowski at quarterback.

  • (19) Tennessee 34, (14) Dallas 27: Tony Romo had nine INTs last season. He had three Sunday.

  • (23) Tampa Bay 24, (18) Cincinnati 21: Throw out Carson Palmer's abbreviated 2008 season and his passer rating has declined every year since 2005.

  • (31) Detroit 44, (24) St. Louis 6: Scott Linehan had to enjoy calling that halfback pass while leading his former team 34-6 with 9:21 remaining.

Still to play: "Monday Night Football" featuring Minnesota and the New York Jets.

My early favorite for the No. 1 spot: Pittsburgh. Ben Roethlisberger makes his 2010 debut in Week 6 for a team that weathered his absence better than I expected.
