NFL teams once again didn't wait until "Black Monday" to take drastic action with their coaching staffs this season.
With Week 18 wrapping up Sunday and the playoff picture complete, four teams already find themselves with vacancies in their top jobs: the New York Jets, New Orleans Saints, Chicago Bears and New England Patriots. History suggests more firings are still to come, with dismissals of key assistant coaches also likely in several spots. And it shouldn't take long for teams to begin moving on their searches, with interview requests sure to start filtering in.
