Jets owner Woody Johnson fired general manager John Idzik and head coach Rex Ryan on Monday.
Ryan bows at MetLife Stadium with a 46-50 record from his six seasons in charge, though that belies the Jets' struggles in recent years.
After reaching the AFC championship game in each of Ryan's first two seasons, the Jets failed to end with a winning record in their subsequent four campaigns, culminating in 2014's dismal 4-12 run which left them bottom of the AFC East.
Ryan has paid with his job for those failings, having reportedly cleared his desk before Sunday's season-ending 37-24 win over the Miami Dolphins.
"After extensive thought and reflection about the current state of our football team, this morning I informed Rex Ryan and John Idzik that they will not be returning for the 2015 season," Johnson said in a statement.
"Both Rex and John made significant contributions to the team, and they have my appreciation and gratitude for their efforts and commitment. Over the years, Rex brought the Jets a bold confidence and a couple of great post-season runs, which all of us will remember.
"I am beginning our search for new football leadership, effective immediately, with guidance and support from respected football experts, including Charley Casserly and Ron Wolf, two Super Bowl winners with decades of valuable experience.
"We will consider all options to improve the Jets."
Idzik is also deemed culpable after two years as Jets GM, which have seen the team go significantly backwards.
The Jets came into the campaign with bountiful salary-cap space after a string of departures including the high-profile release of quarterback Mark Sanchez, but Idzik was unable to add significant quality for Ryan to work with and has too been moved on.
