10. Greg Williams
Williams is one of the shadiest figures in the NFL. ‘Bountygate’ was a major scandal after it emerged that Williams rewarded players for injuring opponents. This occurred during his time as defensive coordinator in New Orleans. The NFL found out and suspended him indefinitely for his actions. Of course, he returned after just a year on the sidelines. It was heavily evil.
Allegedly, Williams ran similar schemes during his tenures in Washington and Buffalo. Both franchises denied this but the allegations haven’t gone away. Nor is it likely that Williams just came up with the idea during his time at his sixth franchise. Furthermore, he never coached a game for the Rams because of his NFL punishment. This was definitely one of the craziest stories in recent NFL history.
