Having worked side by side with Belichick for five years, I honestly knew one day he was going to eventually win a Super Bowl, in part because he was super smart and had a willingness to adapt. He was always divergent in his thought process. He was, and still is, the best listener I have ever been around.

With Belichick, there was never an ego in the room. He only focused on what was urgent and important each day. He had core principles and beliefs he adhered to, never wavering off those beliefs.
