A quarterback might not be selected within the top five picks of the 2018 NFL Draft.

So says one NFL general manager who instead views a running back, Penn State's Saquon Barkley, as the potential first overall pick.

Preseason buzz was centered around the idea that three college quarterbacks — USC's Sam Darnold, UCLA's Josh Rosen and Wyoming's Josh Allen — had the potential to be drafted within the first three picks. But none have stood out thus far in the 2017 season.

"Right now, this isn't a draft where you see a quarterback go top three like everyone was saying, or maybe even top five,” the GM told Sporting News, speaking on the condition of anonymity. "The production isn't there from anyone, and we are what, five, six or seven games in? You don't see it."

Darnold in 2017 has passed for 2,292 yards, 17 touchdowns and 10 interceptions through eight games. Rosen has thrown for 2,620 yards, 19 touchdowns and eight interceptions through seven games. Allen has produced 1,216 yards, eight touchdowns and six interceptions through seven games.
