The Buffalo Bills on Sunday pulled off the biggest NFL upset in 23 years -- and they did it in convincing fashion, routing the heavily-favored Minnesota Vikings 27-6.
The Bills, who were winless entering Sunday's game in Minnesota, closed as consensus 17-point underdogs to the previously-unbeaten Vikings. They are the 15th underdog of 17 or more points to win a game in the Super Bowl era, and the largest underdog to pull off an upset since the Washington Redskins knocked off the Dallas Cowboys 24-17 as 17.5-point underdogs on Dec.
