When defensive coordinator Dean Pees packed up, the Patriots became part of a trend. Already this offseason, a full quarter of the league has, in one way or another, lost their defensive coordinator. That number could grow depending on what happens with the playoff teams and whenever the mess in Oakland is sorted out and turned into a new and different mess.

The Patriots are one of the three teams, along with the Bears and Bills, yet to fill their defensive coordinator vacancy. Here, a quick rundown of all the defensive coordinator moving and shaking:
