The Minnesota Vikings and Philadelphia Eagles fanbases have dealt with an incredible amount of playoff heartbreak in the Super Bowl era.
Minnesota lost four Super Bowls in the span of eight seasons from 1969 to 1976. They haven't been back to play for the Lombardi Trophy since then, but the Vikings did lose four conference championship games from 1987 to 2009. Three of those matchups were by a combined 13 points, with the fourth being a 41-0 blowout.
Philadelphia has made and lost two Super Bowls. The Eagles played in the NFC Championship Game each year from 2001-2003 but never won.
