The Bills beat the Vikings 27-6, and lead 27-0 until late in the game.
Nine plays, 75 yards and 4:59 off the game clock - that's the sort of opening salvo you need when you walk into the lion's den and try to pull off an upset. Buffalo turned those recoveries into 10 points and was on cruise control by midway through the second quarter as the crowd at U.S. Bank Stadium cranked up the boos.
The Vikings had two first downs at the half to 13 for the Bills. Buffalo got the points thanks to a 10-yard run by rookie quarterback Josh Allen, but the Vikings' defense shot themselves in the foot with two critical 15-yard penalties on the drive.
It didn't even point out Minnesota. Linebacker Anthony Barr added some assistance for the Bills by grabbing Allen's facemask. Without Dalvin Cook on the field, Minnesota finished Sunday with a whopping 14 rushing yards.
While McDermott repeatedly said all week, that it would be a joint effort in terms of play-calling on defense, he clearly had enough faith in his defensive coordinator to give him a chance to bounce back.
The Buffalo Bills had been, by far, the worst team in the National Football League through two weeks of the season.
Coming off a 22-point fourth quarter that helped the Vikings rally for a 29-29 tie at Green Bay, there was no reason for the Vikings to be this checked out on Sunday afternoon. Minnesota would actually hold the Bills to a field goal inside the red zone, but three more plays later the Bills would cough up the ball via another sack and forced fumble, this time from Jerry Hughes. That starts Thursday night, when they head to Los Angeles to face the Rams.
