I don't know if this has been suggested yet (and apologies if it has), but what about a royalty payment post-graduation? This could be something to allow the athlete to get a cut of the money their participation and/or likeness generated for the school/NCAA/EA/etc. Doing something like this could allow the compensation to reflect the sport's popularity and player ability (no one buys Madden so they can be the third-string tight end in career-mode). I imagine that there are some sports fanatics out there who would get their jollies out of developing some set of equations to determine the royalty owed to each player. Additionally, if graduation (or at least completion of their years of eligibility) were required to get the royalty check we may see more athletes sticking it out in college and not jumping ship to the pros.
