Coming to Berkeley from Dykes' staff at Ruston, La., are offensive coordinator Tony Franklin and assistant head coach/wide receivers coach Rob Likens.

Gone from the previous staff are running backs coach Ron Gould, an assistant at Cal for 16 years, along with Wes Chandler (wide receivers), Ashley Ambrose (defensive backs) and Marcus Arroyo (passing game coordinator/quarterbacks).

Among the five assistants who were retained when head coach Jeff Tedford was fired on Nov. 20, only Jim Michalczik remained on the staff as of early Tuesday afternoon, according to a Cal spokesman. But Gould and Chandler both said Tuesday that all five holdover coaches were let go.

"Tony Franklin is an innovative and creative mind who is one of the top offensive coaches in the nation," Dykes said in a statement. "He's had a tremendous amount of success producing some of the most prolific offenses in college football."

Franklin, 56, was a 2012 nominee for the Broyles Award given annually to the nation's top assistant coach and one of four finalists for the
