CHAPEL HILL, N.C. (AP) — North Carolina coach Bill Belichick opened his second preseason camp Thursday saying the program is adjusting internal duties with general manager Michael Lombardi on paid administrative leave and the subject of a school investigation. "We're working through some things," Belichick said before the morning's first official practice. Two people with knowledge of the situation said a human resources complaint from a former employee is involved with Lombardi's leave. According to university policy, the length of an administrative leave shouldn't exceed 30 days but can vary based on issues under review. Lombardi's career as an NFL executive had included being the GM of the Cleveland Browns in 2013.
