So why wouldn’t college football let players test the waters and then return to college football if they aren’t drafted, or if they don’t like where or how low they went? First, that approach would cause more players with remaining eligibility to roll the dice and possibly leave, thinning the ranks of college football. Second, it would make NFL teams potentially squander draft picks on guys who then say “no thanks” to playing under a low-round contract for a low-rent team, and return to school in the hopes of landing in a higher slot and/or with a better team a year later.
