Belichick avoided the rows of radio reporters in the hotel lobby and spent much of the morning in a hallway outside the green room for players and coaches, down the hall from private rooms for interviews with ESPN.com, SiriusXM and the ACC Digital Network.

O’Brien believes Belichick’s presence will be transformative in Chapel Hill.
