Known as the Purple People Eaters, the Vikings of Minnesota were the most dominant team in the NFL in ‘69. They compiled a 12-2 regular season record, led the league in scoring with QB Joe Kapp, and had a defense— spearheaded by Alan Page and Carl Eller—that is still considered to be one of the best of all time, allowing only 133 points all season. But in the last Super Bowl before the AFL and the NFL merged, the Vikings were man-handled by the Kansas City Chiefs 23-7, and they would then go on to lose three more Super Bowls in the 70s. Poor Vikings. Always a bridesmaid. Never the bride.
