John Richardson is on the move within the Pac-12.

The former Washington State cornerbacks coach has landed a new position at Arizona, FootballScoop reported. At Wazzu, Richardson was also an assistant head coach and recruiting coordinator.

Richardson would replace Dewayne Walker, who left the Arizona staff earlier this offseason after 2 seasons.

Before Wazzu, Richardson coached at Wyoming and North Dakota State, his alma mater. He was part of Bison staffs that kicked off the program’s string of FCS dominance, winning 3 straight national titles from 2011-13. As a coach at North Dakota State, Richardson helped the Bison lead the nation in scoring defense for 3 consecutive seasons, as they held opponents to only 12.7 points per game in 2011, 11.5 ppg in 2012 and only 11.3 ppg in 2013, according to his Wazzu bio.

Richardson has coached multiple all-conference selections and future NFL players, most notably FCS First Team All-American and NFL player Marcus Williams.

Arizona last season ranked 107th in pass defense as it gave up 258.6 yards per game.
