4. Pittsburgh Steelers
Not all winning streaks are what they seem. Of course, it’s the mark of a true champion if they can win when they’re playing badly. Every team endures hiccups throughout a season and is happy to snatch and a victory. However, the Steelers took this to the extreme in 2020. They went on a remarkable 11-game run to seal their place in the postseason. Usually, analysts would call them Super Bowl contenders at this point.

But few of their victories were actually convincing. Finally, the league found out that the Steelers weren’t a great team after all. They lost four of their final five games. Then, they suffered a humiliating playoff defeat to their division rivals. The Cleveland Browns crushed the Steelers while Ben Roethlisberger had one of the worst games of his life (via CBS Sports). It was incredible after such a good start to the season.
