For Sullivan, here is a former ISU player who is supposedly one of our all-time greats and also happens to be running a successful AAU program in the state. The connections he has may be helpful and his knowlege of the AAU system would be a good test for an interviewing coach. As for his relationship with the current staff, who cares? They'd be gone.
Calling Sullivan an all-time great is a huge stretch, imo. Yes he was great at free throw shooting buts thats all I'll say he was great at.
