6. Arizona Cardinals (Last week: 8)
The Cardinals triumphed past division rival San Francisco and are also 3-0 after three weeks. Wins against San Diego and San Francisco are nothing to look over, especially when Drew Stanton is the starting quarterback. Perhaps there’s a bit of quarterback controversy out in the desert.
What to know: How good is Drew? Stanton hit John Brown on a pair of touchdown passes in the second half to help the Cards take the lead. The 49ers had not allowed multiple touchdowns on passes thrown 15 yards downfield in their previous 37 contests.
