Legally speaking, are there any grounds for UNC towards the NCAA?

Marc Edelman, Sports Ethics Director/Law Professor, on the decision to not allow Tez Walker to play this year and the legal side of everything.

Tez isn’t allowed to play this year, but he can next year, how long could either of these avenues take to resolve if UNC went to court? Is there a lawsuit Tez Walker can file? Marc explains both the textbook answer and a reality answer. What could Tez do to expedite a lawsuit settlement? These changes that made Tez ineligible happened two days AFTER he transferred. If he were to go about the advice of Marc, what could that route look like for him and what makes this scenario a double edged sword?
