re: New NIL Guidelines passed

That may or may not be. It depends on how the NCAA sanctions the school. The fact it may harm the booster’s business isn’t enough to constitute tortuous interference. They have to prove intent to interfere, not simply that it resulted from sanctions against the school. The NCAA could still sanction the school and the fact that a booster suffers harm indirectly will not give rise to tortious interference, even if the NCAA knows that may result in harm to the booster’s interests.
