Cardinals' Carson Palmer: Tosses pick-six in Friday's exhibition

Palmer completed four of eight passes for 37 yards and a pick-six during Friday's preseason loss at San Diego.

Analysis:

The Cardinals' offense hasn't exactly been running on all cylinders through two exhibitions. Granted, John Brown has been absent for the bulk of camp due to a concussion, while Larry Fitzgerald missed this contest with a slight MCL sprain. With two of his top-3 wideouts on the pine for stretches, Palmer has combined for 75 yards and the pick on 7-of-13 passing in four preseason drives. If his safety net (Fitzgerald) carries the ailment into the regular season, the Cardinals likely have the WR depth to endure, but the chemistry between Palmer and the reserve wide receivers appears to be well behind that of the starting trio (also, Michael Floyd).
