Walters, a three-year starter at safety for the Buffaloes and the team's 2008 co-captain and most valuable player, is following former secondary coach Greg Brown to the University of Arizona. Walters, who played for Brown at CU, will work as his defensive graduate assistant.
Hamdan, a backup quarterback at Boise State when the Broncos were coached by Dan Hawkins, is going to the University of Maryland to be an offensive technical intern.
Walters and Hamdan were equipment managers at CU during the 2009 season.
Hawkins announced on national signing day (Feb. 3) that Walters would assist Ashley Ambrose with the Buffs' secondary as a defensive technical intern - the same position Ambrose held for two seasons.
Ambrose, however, was scheduled to assume Hawkins' spot as receivers coach this season before Brown accepted the offer to be co-defensive coordinator and coach the Wildcats' secondary.
But to maintain continuity in the wake of Brown's departure, Ambrose will remain in the secondary, where he played for 13 NFL seasons. Thus, Hawkins still must make an offensive hire to fill out his 2010 staff.
Walters, a Grandview High School graduate, said Brown telephoned him "a couple of days ago" and informed him of the graduate assistant opening in Tucson.
"It was an opportunity for me to get my masters and for my wife and family to get out on our own," Walters said. "We've been in Colorado so long, it's just something we wanted to do."
Walters said he was "excited to see how things are done by a whole new staff . . . I learned a lot from 'Hawk' and coach (Ron) Collins (defensive coordinator). I loved my time at CU, but this will offer a different perspective."
Hamdan's opportunity at Maryland returns him to his roots; he attended high school in Gaithersburg, Md., before signing with Boise State in 2004. Hawkins was hired as CU's head coach two seasons later.
"My family is still here (in Maryland) and it's what I want to be doing," Hamdan said, noting he got wind of the opportunity with the Terrapins at last month's American Football Coaches Association annual convention.
He interviewed with Maryland coach Ralph Friedgen after the convention, and three weeks later was hired.
