For struggling NFL teams the end of the regular season triggers an annual exercise in bloodletting known around the league as Black Monday, and this year has proved no exception as a number of head coaches were fired.

After failing to make the 14-team playoff tournament that will culminate with the Feb. 13 Super Bowl, the Miami Dolphins, Minnesota Vikings and Chicago Bears all showed their coaches the door on Monday in hopes a change will turn things around.

Miami's decision to part ways with Brian Flores was the most surprising firing of the day given the Dolphins won eight of their final nine games after starting the season 1-7.
