To understand the brilliance of Steph Curry, hailed as the best basketball shooter there has ever been, watch him training before a game. An hour before each Golden State Warriors match, Curry is on court, being fed basketballs by assistant coach Bruce Fraser to shoot into the hoop. Then he moves into the corner of the court, practising shots that require extraordinary precision to execute - and Curry makes these even harder, taking the shots off-balance, with one leg off the ground, or leaning back, replicating the pressure exerted by an opponent.
