At the end, this is all the NCAA’s idiocy. When you have kids whose talents produced billions of dollars in revenue for schools, clothing companies, media companies, etc., and their compensation, if they are one-and-done is food and shelter for a few months, a black market is going to exist - it’s inevitable. There’s too much cash at stake for there not to be.
I think it’s safe to assume that every high school kid evaluated as an NBA prospect is at least offered a cash payment, and I’m going to assume they take it.
As long as the NCAA insists on pretending that one and done kids are showing up to school for school pride, this won’t change, no matter who goes to prison.
