Working on ball handling is something that every team and player should do on a regular basis; whether you are a primary ball handler or not. Even post players should be doing dribbling drills because it helps to develop their hands and touch with the ball. Even if it is only for 10-15 minutes a day it matters.
This two ball dribbling drill is great to use as a warm up before practice or a workout because it is going to help work on ball handling, but also to get the player moving and warmed up. Along with it working on ball handling it can be a conditioning drill as well if you extend the amount of time that the drill is done for. Adding multiple stations and players to the drill is also great for competition as well.
