The 49ers are hoping to keep Sorensen around on Kyle Shanahan's staff in a lesser role, just not as the defensive play-caller. Sorensen has spent the last three years in the organization, holding titles of defensive assistant, defensive passing game coordinator and nickelback coach before being named defensive coordinator prior to last season.

Shanahan has officially entered boom-or-bust territory by tying himself to Brock Purdy. If the team and Purdy fail to bring home the franchise's sixth Lombardi Trophy, his tenure will quickly come to an end.
