8. Joe Theismann (1985)
The Washington Football Team has had quarterback problems recently but Theismann was a good leader for 12 seasons. The QB was a two-time Pro Bowler and ensured franchise immortality with a Super Bowl win. But his career ended in a miserable fashion. He never played for the Redskins again after he broke his leg in a game against the New York Giants.

Lawrence Taylor and Harry Carson sacked the signal-caller in brutal fashion. As a result, Theismann endured one of the most gruesome breaks on a football field. This injury shocked the nation because it was so nasty. The consequences of the career and life-threatening injury left Theismann with one leg shorter than the other. His health problems prevented him from playing in the NFL again.
