Rivera puts touch on Chargers' defensive staff

Posted by ESPN.com's Bill Williamson

The San Diego Chargers just announced the hiring of two defensive assistant coaches with ties to defensive coordinator Ron Rivera.

The team announced the hiring of defensive line coach Don Johnson and secondary coach Steve Wilks. Both Johnson and Wilks worked with Rivera in Chicago when he was the team's defensive coordinator. Johnson had spent the past two seasons with the Raiders and Wilks was let go from Chicago.

Johnson replaces Wayne Nunnely and Wilks takes over for Bill Bradley. The San Diego Union Tribune reported Nunnely took a job with Denver on Monday. Bradley was one of four assistants let go by San Diego coach Norv Turner last week, two days after the Chargers were dispatched from the AFC divisional playoffs in Pittsburgh.

The hiring shows Rivera is putting his personal touch on his defense. Rivera did interview for the head coaching job in Detroit last week a day before Tennessee defensive coordinator Jim Schwartz took the job. Don't be surprised if Rivera finalizes a new contract to reflect his new position in San Diego.
