19. 2011 Indianapolis Colts
Opposing quarterbacks sure felt comfortable against the 2011 Colts, completing a ridiculous 71.2 percent of their passes and tossing 25 touchdowns to just eight interceptions. The 2-14 team’s quarterback situation, however, was messy. Neck surgery knocked Peyton Manning out for the season, leaving the task to Curtis Painter (pictured, with Manning), Dan Orlovsky, and Kerry Collins.
