Kevin Sumlin will need to fill another hole in Arizona's coaching staff for the 2020 season after the Star confirmed on Monday that defensive backs coach Demetrice Martin will join first-year Colorado head coach Karl Dorrell in a similar position.Β
Colorado's decision to hire Martin was first reported by the Boulder Daily Camera's Brian Howell.Β
Martin, who was the UA's full-time cornerbacks coach for two seasons, was moved to oversee Arizona's entire secondary once Sumlin hired defensive coordinator Paul Rhoads, outside linebackers coach Andy Buh and defensive line coach Stan Eggen. Martin's departure means Arizona will have a new defensive coach at every position this season.Β
Known for his recruiting prowess, especially in Southern California, Martin has worked in the Pac-12 since he was a graduate assistant at USC in 2006. Since then, Martin has coached defensive backs at Washington, UCLA and, most recently, Arizona.Β
Wildcats begin the spring football practice Monday.Β
