If they want to get paid, they're going to get taxed on everything - strength & conditioning, meals, gear, food, access to facilities, access to private coaching, all of that is not free and not cheap.
These kids have no idea how good they have it. Yes, they should be able to profit on their name, image and likeness. And yes, that's a long time coming.
But the compensation they have been provided - free education, housing, top-end food, weight room access, medical bills for surgeries, athletic training, free gear, on top of marketing their name/brand on national television numerous times. Those things add up to a lot of money.
