This was one of my favorite instructional videos growing up and now you can find it on Youtube!
Coach Holowicki takes you through a progression of dribbling moves and finishing drills starting from the basic and moving up to the complex.
I found this useful as player, because it gave me structured moves to practice. While some are more useful than others, they all bring an element of fun and flash to the game.
Lastly, if you have a few moves that you know you can hit to get you to where you want to be on the court, as well as the counter to those moves, you will be a step ahead of the defense. You can dictate the flow of the game instead of just purely responding to what the defense gives you!
Now get out there and practice some new moves!
