The New Orleans Saints have already lost one important defensive assistant when the Dallas Cowboys hired away linebackers coach Mike Nolan, and New Orleans could risk losing another big part of their success to an NFC East team: the New York Giants, who have expressed interest in defensive backs coach Aaron Glenn.

Per a report from the New York Post’s Paul Schwartz, the Giants are considering Glenn for their open defensive coordinator position beneath first-year head coach Joe Judge. The Giants have already requested an interview with Miami Dolphins defensive coordinator Patrick Graham, so Glenn would be their second option.

Glenn’s role with the Saints has centered around helping scout and develop young defensive backs like Marshon Lattimore, Marcus Williams, Eli Apple, J.T. Gray, and Justin Hardee, much like Nolan did with the linebackers. Under Glenn’s tutelage, the Saints went on to field one of the league’s better secondaries in 2019, with Williams ranking among NFL leaders with four interceptions. His loss would be big, to say the least.

And other teams have tried to lure him away before. Last offseason, the Cincinnati Bengals requested an interview with Glenn, which the Saints blocked. No official request from the Giants has been filed just yet, but it’s very possible the Saints lose more assistants in the coming weeks as coaching staffs are built around the league.
