No doubt Farley has good coaching genes. But what is surprising in that this is not an 'in the family' hire, certainly emphasized in all of the recent moves. If there was no interest by former Cyclone or Toledo players, then no big deal.
I have no doubt that there was interest from former ISU/Toledo players. But, you don't need to have former players for all of the GA's. You get a smart in-state kid from a coaching family that played at a fairly high level, that's not a bad thing. I would think that with the way Campbell has promoted from within, competition for those GA spots was probably pretty fierce. A good way to grow the "family" is to hire good GA's and let them learn in the system.
