15. Lovie Smith
Smith’s obsession with Rex Grossman during his tenure as head coach of the Chicago Bears was borderline creepy. Grossman did nothing of note to validate his coach’s faith. In fact, he arguably cost Smith his best opportunity of winning a Super Bowl. The Bears played the Colts on that fateful night in Miami but squandered a chance to beat their opponents. Smith’s decision to keep Grossman in was a key factor.

They made the final, but Grossman didn’t have a great individual season and only played two more games as the Bear’s starter after this. He literally threw the game away in the fourth quarter with one of the laziest passes ever seen in the event. Furthermore, his overall effectiveness to that point was minimal with just 44 yards through three quarters of play. But Smith was too stubborn to take him out.
