Josh Rosen already has a relationship with veteran Packers quarterback Aaron Rodgers. Now the Cardinals' QB will learn from a coach that helped develop Rodgers.

The Cardinals have officially hired veteran NFL assistant Tom Clements as their passing game coordinator and quarterbacks coach, serving as the de facto offensive coordinator given that head coach Kliff Kingsbury will call the plays and run the offense.

A portion of the coaching staff had previously been announced: Defensive coordinator Vance Joseph, offensive line coach Sean Kugler, special teams coordinator Jeff Rodgers, linebackers coach Bill Davis, tight ends coach Steve Heiden, wide receivers coach David Raih and assistant offensive line coach Brian Natkin.

The 65-year-old Clements has been out of the NFL the past two seasons, after spending 11 seasons with the Packers as a quarterbacks coach, offensive coordinator or assistant head coach, joining Rodgers in Green Bay in Rodgers' second season, when Brett Favre was still a Packer.

Clements' first NFL coaching job came in 1997, and he has served as quarterbacks coach for the Saints, Chiefs and Steelers in addition to spending two seasons as offensive coordinator of the Bills.

A one-time star quarterback at Notre Dame, Clements was in the NFL only one season (with the Chiefs) but was a star QB in the Canadian Football League for 12 seasons, winning the league's Most Outstanding Player award in his final year of 1987 and also being part of two Grey Cup champions.
