Every year, Football Outsiders puts together a list of the NFL's best and brightest young players who have barely played. Eighty percent of the draft-day discussion is about first-round picks, and 10 percent is about the players that should have been first-round picks, but instead went in the second round.

This list is about the others. Everybody knows that Marcus Mariota and Myles Garrett are good. There's a cottage industry around the idea of hyping every draft's No. 1 quarterback as a potential superstar. This is a list of players that have a strong chance to make an impact in the NFL despite their lack of draft stock and the fact that they weren't immediate NFL starters. (Our full criteria for who's eligible for this list is at the bottom of this article.)

Previous instances of the list have hyped players such as Geno Atkins, Elvis Dumervil, Malcolm Butler and Jamaal Charles before they blew up. Last year's list included David Johnson, Danielle Hunter and Super Bowl star Grady Jarrett.

This year, there weren't any prospects head-and-shoulders above the rest of the crew, like we've seen in past instances. Last year, for example, David Johnson was an easy top prospect. We actually had to have a bit of a debate to settle on the top of the list.
