2017 was another hard year for the Cardinals. David Johnson and Carson Palmer suffered injuries early in the season. Midseason, former Minnesota Vikings running back Adrian Peterson was acquired from New Orleans, but was also shut down after a neck injury suffered late in the season. The Cardinals finished 8-8 without the playoffs. This season marked the end of the Bruce Arians era in Arizona as he retired following the season. Carson Palmer also retired the next day after 15 seasons.
