Even when things change, everything stays the same for the Arizona Cardinals. Despite unveiling what is essentially a revamped defense with linebacker Daryl Washington in the lineup, the Cardinals remained at No. 19 in Week 6 of ESPN.com's Power Rankings. Arizona showed its defense is not only formidable but a force. It sacked Cam Newton seven times, intercepted him three times and shut him down on the ground in the second half, not giving up a single yard.

But for as good as the defense was, the offense wasn't, especially in the first half. It was able to find a rhythm after halftime, which, while promising, still leaves people wondering why it can't put together drives earlier. There were a few good signs. The offense drove 85 yards in the third quarter, which resulted in a touchdown. After Antoine Cason returned a fumble to the Carolina 9, the Cards were able to capitalize on the short field with a touchdown pass to Jim Dray. Those plays showed the offense is capable of producing, but it needs to start sooner.
