For all of their popular failings, there are teams on the other end of the spectrum, who have won every Super Bowl that they have made it to. Those teams are: Baltimore is 2 for 2, and the Saints, Jets, and Buccs are 1 for 1.
But no team who has been to more than 2 Super Bowls has a perfect winning percentage.
And every team who has been to more than 2 Super Bowls has won at least once (other than the afore mentioned Bills and Vikings).
Teams who have been to multiple Super Bowls include the likes of: Miami, New England, Dallas, Pittsburgh, Oakland, Green Bay, and so forth...
So the question is, of the teams who have been to more than two Super Bowls, which team has the best winning percentage?
