Six-time Super Bowl champion Bill Belichick is continuing to explore the head coaching opportunity at North Carolina, ESPN reported Monday, with a resolution expected by the end of this week.Multiple outlets previously reported that Belichick interviewed with the Tar Heels last week in New York, and according to the Raleigh News & Observer, Belichick “blew them away in the interview.”However, there are concerns about his age — Belichick is 73 — and the fact that he’s never coached at the college level, per reports.After he and the New England Patriots agreed to part ways following a 24-year stint, Belichick interviewed for the head job with the Atlanta Falcons, who instead hired Raheem Morris. The North Carolina interview is the first known instance of Belichick showing interest in a college position.Belichick is expected to draw interest for NFL openings in the upcoming hiring cycle.The Tar Heels retained an outside advisory firm to identify coaching candidates to replace Mack Brown, whom they fired at the end of the regular season. North Carolina went 6-6, including 3-5 in the Atlantic Coast Conference.
