Josh Allen’s running ahead of the record books the past three weeks.

It hasn’t always been his game.

“I was extremely slow in high school,” said Allen. “I wouldn’t say I’m fast now, as I went through junior college, got to Wyoming, I actually started hitting the weight room and I guess kind of evolved as an athlete there.”

But it has become the big leap of his rookie year.

“Now it’s not surprising anymore. I think it was the Vikings game where he took off and he hurdled Anthony Barr. It was like, damn this kid’s for real,” said safety Jordan Poyer.

It's all part of Allen’s continued development.

“I think for the most part he’s been on time with it, and so he’s letting routes develop and if there’s separation, great. If there isn’t, then he’s’ got to do something with the ball to create a play for us,” said head coach Sean McDermott.

McDermott calls Allen’s running a weapon, but can put on his defensive coordinator hat to see it as a headache — one which Allen himself says is rooted by instinct, not scheme.

“We’re not really calling quarterback runs 10 times a game; we maybe had one or two this past game. They usually come on broken plays or I feel like options 1, 2, 3 might not be there and I feel comfortable tucking the ball and try and get the first down,” said Allen.

“It’s probably pretty frustrating trying to play against him. He’s big, he’s strong, he gets out of a lot of bad situations, and he’s able to use his legs and make plays,” Poyer said. “I’m glad he’s on our team because I see some third downs and there’s nothing there and he takes off and it’s just like, ‘yes.’”

We’ll see if Allen allows the ink to dry in those history books when the Bills host the Lions Sunday.
