Nope. Belichick didn't even play NFL. My guess is that at some point sport will mature to the point whereby people finally realise playing and coaching are two completely separate disciplines. Being a good player does not make you a good coach - most of the best players make rubbish coaches.It's not all pure tactics epecially in a game like Aussie Rules, have to have the respect of your players on the field for how you played the game yourself. Imagine being coached by a Jack Darling ffs.
