16. Greg Williams
Williams coached the Buffalo Bills from 2001 to 2003. To say they were bad is an understatement. In sum, they were horrendous under his stewardship. His first season saw them finish 3-13. This improved to 8-8 in his second year but regressed to 6-10 in his final season. By that point, the Bills fired him for being generally useless as a head coach.

Most famous for the bounty scandal with the New Orleans Saints, Williams allegedly ran a similar scheme with the Bills. It didn’t help them much though as their defense struggled to keep the opposition out. Williams regularly attempted to deflect blame onto his players instead of owning up to his mistakes. In short, it was a dark spell for the Bills as he ran them into the ground.
