The Detroit Lions' coaching staff has undergone the biggest changes yet this offseason under fifth-year head coach Dan Campbell.

It’s been a long time coming, but Ben Johnson (Chicago Bears) and Aaron Glenn (New York Jets) are off to run their own franchises. Who they take with them is the next question, but what we do know right now is that Dan Campbell is tasked with replacing two of his closest confidants in the middle of a Super Bowl window.

It's hard to think of another NFL team that's being punished for their success as much as the Detroit Lions are right now. After losing both of their top assistants to head coaching jobs, the rest of the coaching staff is just continuously getting plundered.
