Might be a make or break year for Leinart, might simply be complete chaos in Arizona.
The Cardinals have to fight off the "losing Super Bowl team jinx". Then, if they can fight that off, they have to fight off the 49ers, who seem to be on the rebound. After that, there is the Seahawks, who were down due to injuries, and then the Rams, who are due for a comeback.
Gonna be a tough season for the Cardinals to deal with, and any sort of QB controversy could effectively sink them by November if they aren't careful.
