The school announced the addition of Kaufman on Wednesday. He was the defensive coordinator and linebackers coach at Cincinnati last season.
Kaufman has developed some of the nation’s leading defenses during a 32-year collegiate career, including 12 years as a defensive coordinator.
Cal demoted previous defensive coordinator Andy Buh to position coach after the Golden Bears fielded among the nation’s worst defenses last season.
The Bears allowed the second-most points in the FBS, giving up 45.9 per game on the way to a 1-11 record.
