DISCIPLINE!
Maxim # 1
He will have ZERO tolerance for unnecessary mental mistakes, unforced errors, and foolish personal foul penalties.
He'll immediately get in a player's a** when they do things that harm the team. And unlike CBJ, CJG will fix it on the sideline - he won't "know more when I watch the film".
Silly, unnecessary 15 yard penalty? Hit the bench and start looking forward to your 12,000 laps Monday!
