Miami Dolphins – 1999
This wasn’t the greatest edition of the Dolphins but nobody expected this capitulation against the Jaguars. Hindsight reveals that Jacksonville was the favorite. But Miami fans knew that this was Dan Marino’s last hurrah and dreamed of an elusive Super Bowl win.

Instead, the Jaguars humiliated Miami with a brutal blowout win. Their 62-7 victory ended his career in the worst possible way. It wouldn’t have been a big deal if the Dolphins competed well but fell short. However, they became a one-and-done playoff team after a garbage display (via Jaguars.com).
