In the NFL, "Black Monday" follows the final week of the regular season. Some teams fire coaching staffs that underachieved and open searches for new regimes in hope of better results.
This offseason, five clubs hired head coaches. The Carolina Panthers, Cleveland Browns and New York Giants chose coaches set to lead an NFL locker room for the first time—one from the collegiate ranks in Matt Rhule.
If the Detroit Lions, Atlanta Falcons and Jacksonville Jaguars finish with a third consecutive losing campaign, we could see those clubs make changes to their coaching ranks next year.
