Super Bowl XL
This remains one of the most shambolic sporting events in U.S. history. Fans expect at least one poor call in every game because human error exists. But the number of ridiculous decisions in Super Bowl XL was beyond belief. Many fans accused the NFL of fixing the game because it was insane.

Ben Roethlisberger’s touchdown in the second quarter was one of the most controversial moments. Then there was a holding penalty that could have gone either way but the Seahawks suffered. Seattle fans resented the officials because they feel they lost a massive opportunity (via Sports Illustrated).
