I think the animosity is not hard to understand.
OSU and PSU do not have any bad blood between them. So hire of DT from PSU, while outside of family and feel bad for Scott, otherwise hard to object.
OSU and Iowa do have bad blood between them. Gilman is from Iowa. Gilman and Smith got into heated exchange at Iowa-OSU match. Gilman knocked Fix out of Olympics.
So there is argument by hiring Gilman shows lack of respect for OSU history.
I think I understand why Gilman got hired. He helps RTC which help with recruiting and development. In fact, I could see argument he is best guy around to help RTC.
But I think OSU has pretty good team in the room, and hope we don't lose it in transfer portal. So that is my concern. If DT can get everyone to stay, and maybe get WH in portal, would make me feel good about hire.
