I’ve always believed that you should practice things that you will actually do in a game. There are so many drills out there that teams do that make no sense to me.
However, ball handling is one skill that I do think can extend beyond game situations. Improving your feel of the ball and how it connects to your hand, arm, and body, can always help. Well, there is no better ball handler in history than Pistol Pete, in my opinion.
Don’t waste all of your time with some of the random drills, but it cannot hurt to try them out every once in a while.
