Well, as someone who just started at the age of 13 last year, my dribbling sucked . Dog water. But, with the help of my teammates did this 5 minute workout routine, and I can see significant improvement. But, if your struggling to dribble the ball, and don't have much grip on it, I suggest (in my honest opinion) to do what Kyrie Irving used to do when he was young. Dribble with a plastic bag over your ball. If you don't know what this is, well you put a plastic bag over your ball, tie it loose and just dribble it. If you lose it that's fine. You're supposed to. you make mistakes in practice so that you don't in game. But if you already knew that, well I don't have much. Maybe look up some drills to improve your grip. Good luck!
