Will the Saints Bring in a Veteran FA CB Before Training Camp?

I know some of us would like to bring in someone because we are very thin at CB and I'm in that group that would like to bring somebody in. But this all hinges on what the Saints think their value is and who fits our defensive scheme. Before they can bring someone in we will need to extend either Ram, Lattimore, Armstead or Williams to create the cap space we need.
