2009: Marc Bulger, St. Louis Rams
In truth, there were multiple seasons in which Marc Bulger could have been named the worst starting quarterback of that particular season. After once looking like the next “unheard of quarterback gracefully commanding the greatest shown on turf,” Bulger suffered through bouts of injuries and inconsistent play as the quarterback of the St. Louis Rams. In 2009, after Mike Martz was dismissed as the team’s coach, Bulger went 1-7 in eight games as the Rams starter, finishing with an abysmal 33.7 passer rating. He never started an NFL game after that, and retired from the league at the end of the season.
