What makes a great coach...... ?

[RavennaAl]

What makes a great coach great? Is it his base tweaking skills, his prowess with the TTQB, his play making ability, or his won-loss record? What percentage of each skill does it take to be considered a great coach?

Example, suppose a guy is the best base tweaker in history. His teams are the strongest around. He never passes the ball, just runs people over with the same running play every time and always wins. Would he be considered a great coach? What if a guy couldn't tweak a base if his life depended on it, but he somehow finds a way to keep his team within reach of an obviously more powerfull team. Even though he never wins, would he be considered a great coach just by his ability to take an inferior team and somehow only looses by 3 points? And what about the guy who can't tweak or design plays, but instead has recievers that somehow get open and he is able to complete 99% of his passes and wins. Is he a great coach? And how about the guy who wins every game he plays under one rule set, but under a different rule or weight set looses. How do you rank him?

I'm not picking on anyone, so before someone gets upset thinking that I'm talking about them, I'm just talking generally speaking. How do you rank a coach? What skills are considered more valuable? What percentage of each skill do you account for? Lastly, how could you design a game to truely measure how good a coach is that would be fair to everyone?
