Do you really think there would be many cases where a kid would just "not work hard" as a football player if he knew it could lead to him not getting to suit up? Right now if they don't perform they just get to transfer elsewhere to play ball. Under the 4 year deal I mentioned, the kid could not just go elsewhere. If he does not choose to put in the work, he would just not be dressed and on the field. He's still a student and on scholarship, but he's not playing. As I said, I think it would level the playing field and have both coaches and recruits much more careful about where/who they sign.
