New Orleans Saints – 2019
The Saints know more about heartbreak than most NFL franchises in recent seasons. In 2019 they endured a brutal defeat against the Vikings in the Wildcard round. Minnesota dramatically snatched victory in overtime. It was crushing for Drew Brees because he believed they had a genuine shot of winning rings (via The Ringer).

New Orleans and bad pass interference calls go together like salt and pepper. Somehow they became the first 13-3 team not to make the Super Bowl. However, they threw away a 10-point lead so they can only blame themselves. But nobody expected them to be a one-and-done team.
