ORCHARD PARK, N.Y. — The Bills took the story of the first two weeks of the season and completely flipped it upside on Sunday in Minnesota. After two blowout losses, they bounced back with the NFL's biggest upset in more than two decades — destroying the heavily-favored Vikings, 27-6. Head Coach Sean McDermott credits his leadership group in the locker room for not allowing the early duds to define their year.

"It’s about developing a young football team. Getting a better feel for who we are, understanding our players," McDermott said Monday in Orchard Park. "I’ve seen progress in the past six quarters compared to the first six quarters, I know that has been mentioned out there and I think it’s accurate. The players worked hard, the coaches have worked hard to get on the same page."

Much of the attention after this win, and throughout the entire Bills season for that matter, revolves around the development of rookie quarterback Josh Allen. The first round pick earned his first career victory in solid and sometimes spectacular fashion, accounting for three total touchdowns and soundly outplaying his counterpart, Kirk Cousins of Minnesota.

"To go into an environment like that, against that type of defense; I thought that he was poised and to be able to see the game in which he has seen it to this point, I think would suggest that he is on schedule," McDermott said.

Offensive coordinator Brian Daboll liked what he saw in his young signal caller's second career start.

"There were obviously some good things for him. [He] was good with his reads for the most part and made some loose plays with his feet," Daboll said. "[There are] a lot of things to still clean up on. I think his footwork is getting better, his eye control and getting the ball out on time is getting better."

While Allen appeared to take a big leap forward, it was his hurdling act over a defender for a first down that had him a prominent feature of the highlight reels across the country. To his head coach, there's a fine line between being aggressive and being reckless when the potential franchise quarterback runs the ball.

"I think that the part is to be calculated, yet aggressive, and he’s an athlete and you saw that. I think a lot of people saw that yesterday with the hurdle, McDermott said. “I’m not going to take that away from him, but there’s a time and a place for it as well, and that’s all a part of an added dimension to our offense. At the end of the day I want him to throw first and run second."

Allen and the Bills will once again play the role of heavy underdogs in the Midwest for a second straight week when they travel to Green Bay to face the Packers on Sunday.
