Evidently you have no idea what the Alston decision was about. Hint, it wasn't NIL, it did not establish NIL and had nothing at all to do with pay for play.
Now, there were briefs written by some justices that indicated they would be sympathetic to true NIL deals but in no way did the Alston decision codify enticing prospective prospects with contracts that were de facto pay for play deals.
So, based on the legal wave, which I have expressed that I believe Tenn is on the right side, the NCAA hastily allowed NIL without a lot of guidance. Many schools became very aggressive with their approach to the new NIL opportunities and we will be finding out shortly how far the courts are going to allow the NCAA go to regulate these deals.
Additionally, Justice Kavanaugh literally wrote in his brief that he believe college athletics were using an outdated amateurism model that no longer applied to the NCAA business model and specifically mentioned collective bargaining. If you would like to read about Alston and the justices briefs, you can find all the info easily using google. The direction of public opinion and recent decisions does bode well for Tennessee's position but it's not settled law at this point for many reasons.
