I'm not sure that I would believe that Miami NIL figure. As I understand it, any NIL deal over $600 has to be reported to the college per NCAA rule, but the college is not under any obligation to report it further. In Ohio I'm fairly certain that the state Supreme Court would require this information be divulged if requested through FOIA. I'm not aware if anyone or any media outlet has yet asked for this information. Perhaps, one of the legal eagles on this board could enlighten us all about the status of Ohio college NIL money on the public record.
Universities hide behind FERPA and HIPAA.
I think you know that that's not a reasonable analogy. There is no federal law protecting the confidentiality of university or NIL collective payments to athletes. The most analogous case is State ex rel. Toledo Blade v. University of Toledo Foundation. This was a 7-0 unanimous decision of the Ohio Supreme Court. NIL Collectives in this regard are very much like university foundations in that their sole reason for existence is to the support the university with which they are affiliated. If a NIL collective associated with a state university in Ohio tries to claim some sort of independence that shields them from FOIA requests as did the UT Foundation, I predict they will be greeted with the same rebuff by the Ohio Supreme Court, if the case gets that far, as did the UT Foundation.
