BERKELEY -- Among the candidates who have emerged to fill two football coaching vacancies at Cal is former Texas defensive coordinator Greg Robinson, who says he isn't inclined to retire at age 62.

A source at Texas told the Austin American-Statesman that Robinson has interviewed with Cal coach Sonny Dykes for the defensive coordinator position that opened when Andy Buh was demoted last week following the program's worst-ever season on defense.

Coachingsearch.com is reporting that one-time USC defensive backs coach Marvin Sanders and recently fired Cincinnati defensive coordinator Art Kaufman also are believed to be on Dykes' short list of candidates.

Dykes has two positions to fill, and needs coaches who can handle defensive tackles and defensive backs, one of whom is likely to be the coordinator.

There are less than three weeks left until the Feb. 5 national signing day for high school recruits, so there is urgency for Dykes to identify for prospects who will be handling his defense.

Robinson, who has served as defensive coordinator for the Denver Broncos and New York Jets, had not coached in two years when Texas coach Mack Brown hired him last summer to work as a quality control coach.

Robinson was elevated to defensive coordinator after the Longhorns were blasted 40-21 by BYU on Sept. 7, and he is credited with settling the Texas defense on the way to an 8-4 regular-season record.

Not retained when new Texas coach Charlie Strong named his staff this week, Robinson nonetheless is energized to continue coaching.

"I've got a lot left in my tank, " Robinson told the Austin American Statement on Dec. 28 before the Longhorns played Oregon in the Alamo Bowl. "I really was considering darkening my hair, but my wife won't allow it. I can coach. I've still got a lot of energy left, and I can outrun a lot of younger coaches, too.

"I got at least 10 more years left in me."

Sanders, 46, currently is head coach at Loyola High in Los Angeles. He coached USC's defensive secondary in 2012, but was not kept on staff when former Cal aide Clancy Pendergast took as over the Trojans' coordinator for the 2013 season.

Reached by phone, Sanders said, "I have not had any conversations." He did not say whether he was expecting to talk to Dykes.

A former player at Nebraska, Sanders coached defensive backs at his alma mater in 2003, when the Cornhuskers set a school record with 32 interceptions. He also served as co-defensive coordinator at North Carolina in 2004.

Kaufman, 55, has coached for 29 seasons, including 11 as a defensive coordinator on the Football Bowl Subdivision level. During Cincinnati's 9-4 season in 2013, Kaufman's unit ranked ninth nationally in total defense (315.6 yards per game) and 16th in scoring defense (21.0).

Bearcats coach Tommy Tuberville made changes on his staff on Jan. 4, saying he wanted a greater emphasis on recruiting the Midwest. "The defense played well," he said. "This is more about recruiting."

Kaufman has coached at Texas Tech and Louisiana Tech -- two schools where Dykes spent time -- but the two did not cross paths at either place.
