4. Arizona Cardinals (Last week: 5)
Despite a rash of injuries on defense, the Cardinals are still pulling out the wins. Their resume to date is very impressive.
What to know: Targeted six times Sunday, Larry Fitzgerald hauled in every single pass thrown in his direction. Fitzgerald racked up 98 yards and his first touchdown since Week 4 of 2013, doubling his receptions and yardage average through the first five weeks of the year.
