17. Rich Gannon (2003)
Gannon led the league’s top-ranked offense into Super Bowl XXXVII. He silenced many of his doubters after an excellent regular season. But it proved to be a flash in the pan. This remains one of the worst choke jobs ever from any sport because it was so bad. If he was a horse, his owner would have sent him to the factory to save him from the humiliation of his existence.

The quarterback threw a Super Bowl record five interceptions in the game. But to make matters worse, Tampa Bay returned three of them for touchdowns. Gannon described his display as a ‘nightmarish performance.’ It’s not a surprise that this haunts his dreams and legacy. He picked the worst time possible to have a meltdown (via Baltimore Sun).
