Frank Solich's service academy recruting brought NU down, but Calahan destroyed the Big Red aura and now Bo has to build from scratch.
I agree with you up to where you say Bo has to build it from scratch. We were devastated by the Solich and Callahan eras, but Bo does not have to build from scratch. We still have first class facilities, tradition and a strongly committed fan base. Those are the first steps of building a program that is a national powerhouse, which many (perhaps most) division 1 programs find to be insurmountable hurdles.
