NFL Hall of Famer Mike Ditka on tonight's Monday Night Football broadcast from San Francisco:
Head coaching isn't about X's and O's as much as people think. It's about dealing with people.
The pic notwithstanding (a cheap shot, I know) Ditka's offhand comment touches on an important truth: Domain expertise, in football or in finance, gets you only so far and no further. At a certain point in your field of endeavor, your success depends less on your mastery of tactics and strategy than on your ability to manage, inspire and lead people who are smarter and more highly skilled than you are.
