2 more former 49ers defensive coaches hired by Robert Saleh, Jets

Two more 49ers defensive coaches are joining Robert Saleh’s coaching staff with the New York Jets.

The migration of coaches from the San Francisco 49ers’ staff to the New York Jets’ staff didn’t end with Robert Saleh and Mike LaFleur heading east. Two more coaches who were with the 49ers last season, Tony Oden and Mike Ruttenberg, will both join Saleh’s defensive staff with the Jets according to reports.

NFL Media’s Tom Pelissero reported Oden would take over as a senior assistant and cornerbacks coach in New York. Oden joined the 49ers’ staff last season as the defensive backs and cornerbacks coach, so his role will be similar with his new club.

Ruttenberg was the passing game coordinator for San Francisco last season in his only year on the staff. He’ll be taking on a new role with the Jets and coaching their linebackers according to NFL Media’s Ian Rapoport.

The 49ers in late January added former Lions defensive coordinator Cory Undlin to their staff. He’ll absorb both the roles vacated by Oden and Ruttenberg. ESPN’s Field Yates reported Undlin would be the passing game coordinator and coach the defensive backs.
