The kill the grass crossovers basketball scoring drill is a great drill to work on your ball handling, but then also work on scoring off of the dribble. Being able to score off of the dribble is a completely different feel than just catching and shooting a basketball. The player must practice doing the different moves and get the feel of getting into their shot off of the dribble.
It starts with having good handles, because if the player can't handle the ball then they won't be able to get the space needed to get into their shot. With these types of basketball drills you are going to pound the basketball as hard as you can and not worry about losing it, because the goal is to make it more difficult than it would be in a game. That way in a game the ball is so much easier to handle.
