Doug Nussmeier is indeed set to continue working with Kellen Moore in 2025. The Saints are hiring Nussmeier as their offensive coordinator, as first reported by Nick Underhill of NewOrleans.Football. 
Earlier this week, it became clear Moore and the Saints were aiming to hire Nussmeier. The two will continue working together in New Orleans as Moore takes on his first career head coaching gig. The Eagles, of course, have already filled their OC vacancy.
Especially after Mike McCarthy was out of the running for the Saints’ head coaching gig, Moore became the top name to watch. New Orleans arranged to speak with him after the Super Bowl, and at that point Nussmeier’s name was mentioned as a strong contender to join Moore in New Orleans. The two have worked alongside each other with the Cowboys, Chargers and Eagles (Moore’s previous OC destinations) and that will continue next season.
Nussmeier’s coaching career dates back to 2001, and on five occasions he operated as an offensive coordinator at the college level. This will be the 54-year-old’s first OC opportunity in the NFL, albeit with a familiar face alongside him. Moore has already confirmed, to no surprise, that he will call plays as head coach.
The Saints’ offense features a number of questions at the moment, and the future of quarterback Derek Carr is uncertain as things stand. Even if the veteran remains in place for 2025, strong play up front will be needed in addition to increased efficiency through the air. During Klint Kubiak‘s one-and-done campaign at the helm, New Orleans ranked 23rd in passing yards. A healthy season from Carr (presuming he is not cut or traded) will help in that department, but in any event Nussmeier’s background as a quarterbacks coach will make him a key figure on Moore’s staff for whichever passer the team uses in 2025.
Other moves have been made in recent days as part of Moore’s efforts to quickly build a staff after taking on head coaching duties in the wake of the Eagles’ Super Bowl win. The Saints’ defensive coordinator position has not been filled yet, but attention can now turn in that direction with Nussmeier in the fold.
