Ian O'Connor, author of "Belichick: The Making Of The Greatest Football Coach Of All Time", joined Brian Kilmeade to discuss how Bill Belichek was drawn into football at a young age by his father Steve and the transformation of Belichek going from being disrespected by his players while defensive coordinator with the New York Giants to winning five Super Bowls with the New England Patriots.

Plus, O'Connor describes how Belichek was able to navigate the backlash he faced from his players after he sent a letter of support to Donald Trump when he was running for President.
