It will be hard for you to guard your man, as well as shoot on the move, and so much more. Big men will have trouble posting and finishing at the basket without good footwork.
However, with great footwork you will be able to build a strong foundation for all of these different skills and be on your way to mastering them. The foot ups side to side footwork drill is going to teach the player to be light and quick on their feet. This footwork and agility workout draws a lot from the sport of soccer (European football).
