Barkley is an Oaks Society member, meaning he has donated more than $1 million to the athletic department.
And BTW, I don't think it is Harsin's place or role to be the point person on raising NIL money. There are people in the Athletic Department Administration and probably the Auburn Foundation whose job it is to do that. I have read that booster groups organize funding at other universities for this purpose. And based on the opinions stated on these forums, Harsin should be focused elsewhere like recruiting, coaching and hiring assistants. Certainly, he can help close the deal on donations, but he doesn't need to be out shaking trees, beating bushes and knocking on doors for NIL money.
