HBO will air a documentary called Belichick & Saban: The Art of Coaching this December on Bill Belichick and Nick Saban.
Belichick and Saban coached together with the Cleveland Browns.
Belichick has gone on to win six Super Bowls while Saban has won six national championships.
The two coaches first met in 1982, when Saban was an assistant coach at Navy, working alongside Belichick’s father.
