Since it was an OSU coach (Woody Hayes) that originated that phrase, calling Michigan "That School Up North". And Ohio State really isn't Penn State'srival anyway--it was Pitt, but PSU doesn't play them anymore. What's Mullen going to do without a rival?
As far as the OP, I think I only really care about losing Wilson, Hevesy, and Balis.Especially Wilson and Balis.There may be some other position coaches that really help with recruiting (Smith), that I should probably care about losing, but I don't really know how important they are.
