Buffalo, a historic 16.5-point underdog to the Vikings, completely flipped the script on an NFC contender, throttling the Vikings 27-6 in a game no one saw coming.
The Redskins were quarterbacked by Heath Shuler, the third overall pick in the 2014 draft who played only four National Football League seasons.
At the end of the first quarter on third-and-9, Allen sprinted straight up the middle out of a collapsed pocket and hurdled Barr 2 yards short of the marker to get the first down. The Bills should have skunked the Vikings, with Minnesota's lone points coming on a garbage-time touchdown with Buffalo spending most of the day up big. Minnesota's running game was little help, adding just 14 yards on six carries. The pass rush was relentless at the start of the game with Jerry Hughes sacking Kirk Cousins and forcing another fumble that the Bills recovered.
Josh Allen is the fifth rookie quarterback since 1995 to win straight up as a two-touchdown underdog, and the first since Joe Webb led the Minnesota Vikings to a win over Michael Vick and the Philadelphia Eagles in 2010. Linebacker Matt Milano had a sack, an interception and a fumble recovery.
Cousins finished 40 for 55 for 296 yards and a late touchdown to Kyle Rudolph. C Russell Bodine, who started in place of Ryan Groy, limped off with leg cramps in the third quarter.
The Bills will look to continue their dominant defensive play against Aaron Rodgers and the Green Bay Packers next week.
