18. Jim Zorn
A few Redskins coaches make this list, but Zorn was one of the most embarrassing. He only managed two seasons in charge of Washington, but that was enough to make every fan hate him. Things actually started out well with a winning start to his first season, but then things imploded after the midpoint, finishing 8-8 overall.
The Redskins could have cut their losses there but instead, they gave him the chance to put things right. In short, they got even worse. Zorn suffered the humiliation of losing offensive play-calling duties to his assistant coach. Meanwhile, he fell out with his players and alienated the fans. It was a terrible time for the Redskins. Dan Snyder definitely won’t unfold the welcome carpet for Zorn.
