Yes, Australian Open winner Novak Djokovic climbed atop the wing of a a bi-plane to play a game of tennis at 150 miles per hour. Why? Well, conceivably to illustrate how amazing a player he is. Because no matter how amazing a tennis racquet Head may make, it's not the racquet that makes this possible. It's the player. Sorry, Adidas.
