Super Bowl's worst teams

10. 1968 BALTIMORE COLTS

Super Bowl III: Few teams in any sport have underperformed on the big stage worse than these 18-point favorites. Coming off a 1967 season in which they lost only one game, they held 11 of their 16 opponents to 10 points or less. But against the Jets, they let Matt Snell and George Sauer run wild, combining for nearly 300 yards of offense. As for the Colts' offense, it was shut out until Jerry Hill's garbage-time plunge with only three minutes left.
