College football teams can have as many as 105 players on their rosters, yet no more than 85 can be on scholarship. The rest must pay their way and are known as walk-ons.
By and large, walk-ons are former standout high school players who weren't considered good enough to earn a free ride but still possess enough value to help a team out in terms of depth and practice flexibility. When a school finds itself with some extra scholarships, sometimes a select few walk-ons will pick up an award for a season or two.
And then there are the success stories, the players who go from nobody to key contributor to star to...the NFL?
Each year, the NFL draft features a few players who began their college careers as walk-ons, completing the ultimate rags-to-riches journey. That list includes current NFL stars such as Green Bay Packers wide receiver Jordy Nelson and Houston Texans defensive end J.J. Watt.
We've identified eight such former walk-ons who have a shot at hearing their names called in New York City this weekend.
