Saints interested in Brandon Staley and George Edwards for defensive coordinator

I don't think that KM being a 1st time HC goes with a 1st time DC no matter how patient the FO will be with him. So I think it's almost a lock that it's Staley. Only other choice would be Martindale, but there have been no links to KM and him.
Unless we make a play for a DC with another team and make him a DC/Ast HC kind of hire
