Pittsburgh Steelers – 2020
Nobody expected the Steelers to amass an 11-game win streak to start the season in 2020. But that’s exactly what happened after they went on a scintillating run. However, analysts believed that their record didn’t reflect their overall abilities. This prediction came through in the postseason after a crushing defeat.

They faced the resurgent Cleveland Browns in the Wild Card round. Ben Roethlisberger had one of the worst games of his career because he threw four interceptions. Finally, the Steelers fell to a 48-37 loss and dropped out of the postseason as a one-and-done team (via Sporting News).
