The Pittsburgh Steelers have been one of the most successful franchises of the 21st century winning two Super Bowls and reaching a third.
As a result, they are often the favorite, but that hasn’t stopped them from excelling when the odds are stacked against them.
According to BetMaryland.com, the Steelers are the best-performing underdog this century with a ridiculous 43.3% win rate against the odds.
Over the last decade they have the second-best win rate at 49.2%. Only the New England Patriots have been better over the last ten years at an even 50%.
The worst performing franchise against the odds is one you would expect. The Cleveland Browns have won just 25.5% of their games as an underdog this century. They have only been successful 18% of the time this century as an underdog as well.
