Two defensive coaching candidates the Saints will consider adding to staff include Eric Mangini and Romeo Crennel, per league sources. It’s even possible the two could go together to New Orleans with one serving as defensive coordinator, sources said. When reached Friday about this possibility, Mangini said he has not been contacted by anybody from the Saints about any position. Mangini and Crennel worked on the same Patriots coaching staff that won three Super Bowls in New England. Saints have told people they plan to proceed with their defensive coordinator search slowly and there’s no rush to fill the position.
