The Bears blocked the 49ers from contacting defensive coordinator Vic Fangio about a return to San Francisco. The plan is for Fangio to oversee the outside linebackers while also serving as coordinator, something he has done in previous stops. Defensive quality-control coach Sean Desai will also work with the outside linebackers. It remains to be seen if Desai will be given a larger title. He has been a quality-control assistant for the previous four seasons, a position that typically turns over at a higher rate.
