The entire defensive coaching staff has to go. The 4-2-5 is dead. Time to bring in a DC and staff who will run a 4-3 or 3-4 and commit to getting the players to run it properly. There is no in-season fix for this lame duck defensive coaching staff with an under-developed rookie DT, under-performing former high first round pick DE, mediocre journeymen DTs, and a DE who should have retired before last season. The secondary is under-developed or just getting too old, linebackers have talent but are underperforming. It is just ugly. The Saints are playing "anti-air" defense in a league that's back to the ground and pound.
