You need sharp eyes and quick and strong hands to be able to block a player. Just oush him to the edge where he has to pick the ball up after dribbling. Then it as easy as hell. Lean over a little ( no dirty minds )making him feel uncomfortable ( try not to foul the guy or hurt him). So then he would either pass to a teammate. At this moment he will keep his eyes of you for a short time, take your chance and hit the ball away from him ( again try not to foul ) do it quick with no hestitaion. if he decided to shoot. Just put your hands up in a line with the basketlooking from the opponent point of view. He cant shoot or either go for a desperate one. Hope it come in useful!
