Cardinals need more from 'D' on road

The Arizona Cardinals scored two touchdowns on defense during their 30-20 victory over New Orleans in Week 5.

They also allowed 401 yards rushing in their previous two home games.

"Inconsistent" was the word coach Ken Whisenhunt used to describe Arizona's defense during a media conference call Wednesday.

"At times, we've shown we can be a pretty good defense," Whisenhunt said. "At times, we've been flat awful."

Pretty good: picking off Drew Brees three times at University of Phoenix Stadium.

Flat awful: allowing 868 yards and 74 points during defeats to the Atlanta Falcons and San Diego Chargers (the Chargers also scored on an interception return).

The Cardinals have played three of their first five games on the road, which hasn't helped. They've also had quarterback issues, tossing five interceptions in those three road games (and only two at home). Those turnovers have put the Cardinals' defense at obvious disadvantages, fueling a home-and-away stat imbalance on defense. Arizona's offense failed to convert even once on third down during a 41-7 defeat at Atlanta.

Opponents have also pushed around the Cardinals' defensive front at times, particularly during that loss to the Falcons.

The chart shows Arizona's defensive averages per game at home and on the road this season. The team has allowed fewer first-quarter points per game on the road (4.7) than at home (11.5), but opponents have outscored the Cardinals 48-24 in second quarters away from University of Phoenix Stadium.
