A great way to get separation from an aggressive defender is the threat of being able to break them down off of the dribble. You hardly ever see a player like Chris Paul, Tony Parker, or Rajon Rondo being over pressured, and the reason is because they are able to handle the basketball and breakdown their defender if they get too close to them.
This basketball dribbling drill is going to work on selling your in and out move, and then immediately getting into the next dribble move. When you watch the player in the video doing the drill make sure that you watch how he is selling the move, and also how he is making the move as quickly as he can. Whether you ever use this actual move in a game or not, you will still be working on your over all handles with this drill.
