It would seem likely that a Super Bowl loser would have a good shot at returning to the Super Bowl the following year and winning it.
They have the incentive of overcoming the loss the previous year to give them motivation.
And that’s what often happened in the early days of the Super Bowl.
The Dallas Cowboys lost to the then-Baltimore Colts in the fifth Super Bowl, then beat the Miami Dolphins in the sixth one. The Dolphins then came back in 1972 and had their unbeaten season and won the seventh Super Bowl.
Believe it or not, that is the last time a Super Bowl loser has won it the next year.
