The Buffalo Bills are set to carry just two quarterbacks into their season opener against the New England Patriots.

And they're both rookies.

With just EJ Manuel (first round) and Jeff Tuel (undrafted) on their 53-man roster, the Bills would become the first team since at least the 1970 AFL-NFL merger to carry two rookie quarterbacks on their roster, according to Grantland.com's Bill Barnwell.

In his team-by-team previews, Barnwell sees the decision as a calculated risk by the Bills:

In a way, you can't really blame the Bills for taking the high-risk, high-reward route. If Manuel is awful and the Bills go 3-13, Buffalo likely ends up with an extremely high draft pick in what's shaping up to be an excellent NFL draft next year; you can certainly imagine how nice Jadeveon Clowney would look on the Buffalo defensive line next to Marcell Dareus, Kyle Williams, and Mario Williams. Or maybe they end up with Teddy Bridgewater, who profiles as much more of a can't-miss prospect than Manuel. Or, hey, maybe Manuel is good and the Bills find themselves a starting quarterback who will last for four full years as the starter for the first time since Jim Kelly.

It's an all-in approach by the Bills, who have the NFL's second-youngest offensive coordinator (Nathaniel Hackett, who is 33), a first-year head coach (Doug Marrone) and a first-year general manager (Doug Whaley).

Marrone was asked Sunday if he sees any problem in carrying two rookies at quarterback, forgoing an opportunity to bring in an experienced veteran to steady the position.

His answer, in brief? No.

"No, I don’t. I don’t worry about it. ... I think that’s our situation and we feel that we’re going to go into it with the players we feel give us the best chance to win," he said. "I don’t have a problem if someone is a rookie, a veteran, whatever it may be."
