In the NFL, teams routinely come out of nowhere to make the playoffs or go on deep postseason runs.
Last year, the Tennessee Titans went on a miracle sprint to the AFC title game, while the San Francisco 49ers went from 4-12 to 13-3 and booked a spot in the Super Bowl. Both teams appear to have a good chance at proving those 2019 campaigns weren't flukes, but it wouldn't be shocking if they were.
Some of the most notable fluke seasons in league history featured teams shooting to solid records seemingly out of nowhere and with a big assist from luck, outside factors or even a gimmick.
