the biggest problem i see is that when it comes (and it is coming, i can't see anyway this doesn't end up with some type of payment system) i think we're going to go full bore open payment/no scholarship. the pendulum will swing fully to the other side, as is tradition in the overtly reactionary society we live in now. which will be disastrous, imo. especially if we're doing it under the guise of fair play and increased parity.
i'm afraid it will unlevel the field even more (i know, har har, that funny coming from a bama fan).
second, imo it will hurt, not help, most players. i mean the vast majority. even for bama, most players aren't going to have the name recognition to make a decent living while in school if they have to pay for tuition, room/board, food, clothing, tutors, etc. the big names, (tua, hurts, jeudy, etc.) will be fine. better than fine. even the middle ground players will get some endorsements, but i doubt it'll be that much. maybe a few hundred to do a commercial or 2. another hundred to do an auto session. but i have serious doubt's they can make enough to cover their expenses without the benefits of their scholarship. and then there's the lower end players who won't even get a shot at endorsements most time. and that's at bama, arguably the most crazed fanbase out there. and don't make the mistake thinking the bama alumni don't have the means to support players. we might not have the biggest endowment or the most wealthy fanbase, but we've got our fair share of heavy hitters with more than enough means to pay those guys (and have in the past, lol)
that's why i like the choice model. i haven't hashed it out fully, so i'm sure it has some flaws i haven't thought of, maybe even major ones (probably). but so far, it's the best suggestion with a decent middle ground.
