California has formally announced the hiring of Garret Chachere as defensive ends coach and Zach Yenser as offensive line coach, which means new coach Sonny Dykes has filled out his staff of nine assistants.
Chachere coached tight ends coach and was special teams coordinator at Southern Miss last year. He had spent the three previous campaigns at Arizona coaching receivers. From 1992 to 2006, including eight years at Tulane, he coached almost exclusively on defense.
Yenser was the assistant offensive line coach at Louisiana Tech in 2012. He was a four-year starter at Troy, appearing in 42 consecutive games from 2003-06.
Here's a bit of perspective on the hires.
