Not every team passes the midterm exam

It's midterm exam time in the NFC, and Scouts Inc. is handing out the grades.

Here are the grades for the AFC.

Arizona Cardinals (3-5)

Right answers: This is a team that went from the 29th-ranked defense in 2006 to being ranked ninth heading into Week 10. Coach Ken Whisenhunt made a few changes in personnel, but more importantly, he installed a new attitude. The defense has been able to keep this team in games long enough to allow the offense to pull out late-game wins against Seattle and Pittsburgh.
