I am not familiar enough with the inner workings of the NC State program to tell you why they are able to fund raise at higher level than Pitt. Looking in from the outside Pat Pop is heck of a coach who had proven prior to NC State that he is able to create a winning culture at a school with little to no history.
Outside of the one mega donor that loves the sport you generally need a history of past success that donors want to recapture or recent success to get people excited.
I was of the belief that Nino winning an NC would have a bigger impact on recruiting but the lack of international free style success and the lack of NIL are hurting. Now with NIL it makes it easier for the wrestling clubs (PWC, NLWC, Ohio RTC, etc.) funnel money to college athletes Pitt is even further behind when before it was a little more gray with only a few doing it.
I hate what ifs but I have no doubt that Pitt wrestling would be in a much better place if they would have hired Pat Santoro instead of Gavin.
