Vince Lombardi on the separator for his championship teams:
"There are a lot of coaches with good ball clubs who know the fundamentals and have plenty of discipline but still don't win the game. Then you come to the third ingredient: if you're going to play together as a team, you've got to care of one another. You've got to love each other. Each player has to be thinking about the next guy and saying to himself, "If I don't block that man, Paul is going to get his legs broken. I have to do my job in order that he can do his." The difference between mediocrity and greatness is the feeling these guys have for each other."
