This is pure speculation, but if I were guessing the most likely potential violations, I'd say tampering with Sid Wilson while he was at St John's (remember a certain insider posting we might get 2 Brewster players before Sid had left St John's and before Kisunas committed?), and maybe investigations into whether inappropriate contacts were made to Montez Mathis, Cam Reddish. Jalen Carey, Mo Bamba (remember Okafor and Diarra practicing with him in New York?), Tremont Waters (remember Ray Allen happening to meet him at the Jordan classic?), and/or Hamidou Diallo. All of those players were of high importance to the staff at a time when they were struggling. Then the NCAA probably conducted interviews with the transfers assuming that they might have ill will against Ollie and would spill any beans in exchange for a promise of immunity. That's 7 recruits + 3 transfers and if you interview them plus 4 others per player who had knowledge of the player's recruitment, 2 hour interview per person, you would have 100 hours of tape.
