no it isn't. because they provide value to the athletic department that is much much greater in terms of dollars than the price of tuition, board, and per diem. they deserve to be paid a fair percentage of the revenue they generate for the school's athletic department. if that is greater than the price of tuition, room and board, they deserve the extra compensation.
especially in cases like these. remember this qb only has a couple years of college to cash out as much as he can, as he is not going to be in the nfl.
imagine your on your job and get your company a $10 million business deal. the deal closes and you ask for a $100,000 bonus as a reward for getting the company $10 million.
company says "we already pay your mortgage isn't that enough?"
you would leave that job immediately.
