The Bill Belichick era has gotten off to a rough start in North Carolina. The legendary head coach has secured just two wins in his first five games as the Tar Heels' head coach, and there are rumors of him either stepping down or getting fired.Either decision would come as a huge letdown for the North Carolina faithful, just months after they celebrated the future Pro Football Hall of Famer's arrival. With the rumous getting louder, let's look at three potential Bill Belichick replacements.3 coaching candidates to replace Bill Belichick if he gets fired3.
