Four National Football League head coaches got fired in recent weeks, while another decided to "step down." But teams got more wins for their money out of those coaches this year than some franchises that kept their coaches.

Former Philadelphia Eagles head coach Chip Kelly.

The Philadelphia Eagles started the round of firings before the season even ended in late December, cutting ties with head coach Chip Kelly. The Cleveland Browns, San Francisco 49ers and Tampa Bay Buccaneers all sacked their coaches after play concluded, while the New York Giants' Tom Coughlin resigned after losing 10 of 16 games this season.
