Dewayne Walker says Arizona cornerbacks are in good hands with their new position coach.

Walker announced a parting of ways with Arizona on Sunday via Twitter. Monday, he used the social media platform to praise his successor, John Richardson. Walker, a well-traveled coach, considers Richardson a rising star in the coaching field.

Walker, 62, left Arizona after 2 seasons on staff, his 34th year of coaching football. As Walker notes, Richardson arrives with Pac-12 familiarity. Richardson joins Jedd Fisch’s Wildcats coaching staff after 2 seasons at Washington State.

Richardson, a Compton, California native, also coached at North Dakota State, his alma mater.
