NIL is not, currently, offered by the school.
If you have a scholarship in school AND a second source of income, the school can't say "you make too much money to have a scholarship" like the govt does with school grants.
Would you deny a normal, non athlete, highly intelligent student who earned a full ride scholarship academically but who was also a multi million dollar model the scholarship they earned via academics? Why?
They EARNED it academically and deserve it, regardless of their income elsewhere.
It is the same for an athlete. They EARNED that scholarship and their outside income shouldn't matter.
As an example, Bronny James is on scholarship at USC. LeBron could easily afford to cover his tuition. In your eyes, he's too rich to get a scholarship?
You'd discriminate against the rich?
