The title of this post is a quote from the legendary John Wooden, and for my money, it is the absolute truth.
Coach Wooden was not only the "Wizard of Westwood," but he is a very intelligent man whose insight should not be overlooked nor pushed aside. One of the most amazing facts about him as a coach - at least I find this very fascinating, is that he did not study film or scout opponents. In Coach Wooden's mind, his teams did not need to worry about their opponents did or were going to do. As long as they executed his game plan, they should win. (Not sure why more coaches didn't try this philosophy. After all, Coach Wooden only won 10 NCAA National Championships.)
