Since I can’t speak for Curtis, I can’t shed much light on what that was about.
What I can tell you is in the short-term, the room will be led by assistants Jeff Imamura and Richard Rogers. From there, Ron Rivera has some options. He could let both continue sharing responsibilities or promote one into the lead role.
Or Rivera could look outside the building.
Perhaps he'll consider calling Hall of Famer Rod Woodson, who helped coach the Raiders secondary the past three seasons. Or maybe Rivera could talk defensive-minded former head coaches Chuck Pagano or Steve Spagnuolo into coming to Carolina.
