Dan Hanzus shares his takeaways from the first half of the preseason opener between the New Orleans Saints and Arizona Cardinals.

The Arizona Cardinals invested plenty of time and money in Kevin Kolb. But injuries and uninspired play have left the quarterback fighting for his job with John Skelton.

Arizona Cardinals coach Ken Whisenhunt said he wants Kevin Kolb to be the team's No. 1 QB, but the coach made it clear that the high-priced free agent still has to win the job, Brian McIntyre writes.

The Cardinals ranked near the bottom of the league in completion percentage and threw the third most interceptions, but with improved quarterback play Arizona still has a shot at the playoffs in the NFC West.
