Arizona Cardinals – 2020
The Cardinals had a bizarre 2020 because they offered a lot of promise before crushing their fans’ hopes. They showed that it’s impossible to take anything for granted as they burst out of the stables with a 5-2 record. In the end, they only won three more games all season as they missed out on the playoffs by a single win (via USA Today Sports).

One Zane Gonzalez kick against the Patriots could have changed the entire narrative. But they were on par or below the expectations of most NFL followers before the season. Many identified them as potential dark horses but they didn’t even make the postseason. There are no guarantees in the NFL because of the ruthless nature of games.
