After a crushing playoff loss in January 2005, then-New York Jets coach Herm Edwards decided to change offensive coordinators. He fired Paul Hackett after four seasons and hired Mike Heimerdinger and did it so quickly that Hackett and Heimerdinger actually crossed paths that day in the team facility. As Hackett went in to clean out his office, Heimerdinger arrived to start his new job.
That snapshot pretty much sums up the history of the Jets' offensive-coordinator job, which should be sponsored by a famous burger chain: In-N-Out.
The Jets will go into the 2018 season with their sixth offensive coordinator in the past eight years, making it one of the least secure jobs in the NFL.
