For me it's either the New England Patriots or the Pittsburgh Steelers. Since 2000 the Patriots have appeared in four Super Bowls and have won three. The Steelers have appeared in two Super Bowls and have won both and have a chance to add a seventh championship this Sunday. Another team that can be added to the discussion is the Indianapolis Colts, they've appeared in two Super Bowls and have won one. What do you think?
