Regardless, he is a winner.
Some might say he has had great talent. I disagree. Plenty of teams with great talent have not been able to win s***.
You can have a 12 cylinder Lamborgini, but if only 4 of those cylinders are firing in sync, you might as well have a Prius.
His job, and I believe he has the ability, is to set the enviroment, create buy in for the mission, give tools for sucess and make solid in game and pre-game decisions.
Keep all 12 cylinders tuned and firing all at once.
I think he is a winner and can breed winners!
