After five years in charge, Bruce Arians will reportedly retire as the Arizona Cardinals head coach.

ESPN's Adam Schefter reported Monday that Arians will walk away from coaching on his own terms.

The 65-year-old leaves having compiled a 49-30-1 record in 80 regular-season games in Arizona.

The Cardinals improved immediately upon Arians' arrival in 2013. The team's record went from 5-11 in 2012 under Ken Whisenhunt to 10-6, and Arizona missed out on the playoffs by one game.

Arians has built a reputation as a quarterback guru, and he more than justified the moniker through his work with Carson Palmer.

In his final year with the Oakland Raiders in 2012, Palmer had 4,018 yards, 22 touchdowns and 14 interceptions. He averaged 267.9 yards per game and had an 85.3 quarterback rating.

Over his first three seasons with the Cardinals, Palmer averaged 278.2 yards per game and boasted a 94.2 quarterback rating. At 36 years old, Palmer threw for a career-high 4,671 yards and 35 touchdowns in 2015, while his 11 interceptions were his fewest in a season in which he played in at least 10 games.
