Big changes have already begun for the New Orleans Saints this offseason, and more are on the way as the team works to enact Kellen Moore's vision. One big move was the addition of Brandon Staley as their defensive coordinator. The former Los Angeles Chargers head coach is highly respected around the league as a defensive play caller, but his odd-front system has some major differences from what Dennis Allen ran for the last decade.
So the Saints will need new personnel to run it, at least at some position groups like defensive tackle.
