When you are winning, you can't run out the clock, play prevent defense, or a neutral zone trap. You have to start a new game at 0-0, win it, and then do it again, and again. When you are mentally and physically depleted, you have to rely on your own abilities, your own instincts, and your own game plan. No one is beside you to calm you down, rev you up, point out your tactical flaws, confirm your strengths, or give you advice on how to exploit your opponent's weaknesses. Speed, power and aggressiveness is a recipe for tennis success. Counter attacking, precision, and patience is a recipe for tennis success. Once a player becomes the best in the world, a generation of of young tennis players try to copy his style. And every time, number 1 is eventually unseated by a rising star who ignores convention and wins with a new game that has little resemblance to what preceded it. Tennis is the greatest game.
