14. Steve Spagnuolo
Spagnuolo was the defensive mastermind behind the New York Giant’s Super Bowl win over the Patriots in 2007. This convinced the St. Louis Rams to offer him his first head coach role. Typically, things didn’t work out the way he wanted them to. The Rams finished 1-15 in his first season, the worst in the league and in franchise history.
Somehow he managed to stay another two years. They did improve to 7-9 in his second year but regressed to 2-14 in his final season. ‘Spags’ is genuinely a brilliant defensive coordinator, but couldn’t organize his team week-to-week. His win percentage is the second-lowest in Rams’ history.
