Mystery, expectations surround the Tar Heels as Bill Belichick readies to coach a college football team in competition for the first time.

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.

Much remains unknown about the Tar Heels’ on-field product, but Chapel Bill’s presence loomed large over the proceedings in Charlotte on Thursday.
