There are vast differences in the institutional support between the 3 programs in the triangle area. My understanding is NC State has pretty good commitment from the institution. Duke has very little- wrestling is unfunded, meaning no scholarships for wrestling and no help getting the wrestlers in school. UNC is in between. Pop has done an amazing job, but more resources and support than Coleman had at UNC.
They all compete in the ACC, but much more to evaluate their potential success at a place like Ok State than record, number of AA or champions at different schools.
