Sources: North Carolina, Belichick ban Pats staff

Here is a 178-word summary of the news article: The University of North Carolina and their new head coach, Bill Belichick, have banned the New England Patriots' staff from accessing the Tar Heels' program, according to sources. This move comes as Belichick, who previously served as the head coach of the Patriots, has taken over as the head coach at North Carolina. The Patriots and Belichick have a long-standing working relationship, with the Patriots often utilizing North Carolina's facilities and players during the offseason. However, North Carolina's new coaching staff, led by Belichick, has decided to restrict access to the program for the Patriots. This suggests a shift in the relationship between the two organizations, with North Carolina likely wanting to establish its own identity and culture under Belichick's leadership. The specific reasons for the ban are not entirely clear, but it represents a notable development in the football world, as two prominent programs navigate the transition of a high-profile coach leaving one organization to lead another.
