Bill Belichick's publicist reportedly assured the North Carolina head coach that his viral interview with CBS would focus on his new book.

Per TMZ.com, Belichick was “furious” when the CBS interview strayed beyond book topics. Then there’s this: “Sources say Belichick had actually shot down several interview opportunities Kass had put in front of him over concerns the media outlets would use his book promotion as a way to pry into subjects not related to the actual book.”
