Look at Cook’s head when he is nicking off at the moment. It is above or behind his front knee. He is not heading down the ground and a strong guy like that opening the innings with a build like Hayden should be hitting the ball straight. The cover drive is the easiest shot in the world to play. Every kid can do it so why not someone as talented as Cook? Batting is all about hitting balls in straight lines. A guy who has scored 25 Test hundreds can change his game slightly and start driving off the front foot.
