The document discusses a basketball player who had spent many hours practicing his shooting alone but struggled during a championship game. While the player could make shots during warmups without defensive pressure, he was unable to get shots off when defended closely in the actual game. The document argues that simply accumulating practice hours is not enough - skills need to be practiced under competitive conditions and at game speed in order to truly master them. Players must get quality reps that simulate actual game situations if they want to effectively apply their skills during matches.
