#NailedItWhat walk-ons contribute to the team is not measured in NFL talent.
Walk-ons are usually local kids, who are willing to give their ALL for the program, and the coach. Not like Calibraskans, who are basically mercenaries for hire.
The walk-ons typically outwork the scholarship players, and the scholarship players learn from the walk-ons just how hard THEY have to work to get/keep a starting job.
