I'm guessing the concern is that, if the head of a company is also a booster, he could find any excuse to use the likeness of a kid whose way he wishes to pay . . . so that his favorite team benefits. Personal profit in this case, is not the consideration.
I didn't take the time to read the article, though . . . not sure whether there is any sort of cap on what a kid can "earn" under this model?
Exactly what I meant. A car Dealer, Golf resort owner...etc. I put your face on a billboard and pay you a King's ransom. The recruits will be lining up for their "endorsements".
