Dan D'Antoni's 'Organized Chaos' Man-to-Man Defense

Longtime coach Dan D'Antoni has guided Marshall to two postseason berths while maintaining an aggressive, up-tempo style of defense. By pressuring the ball and containing to one side of the floor, his teams have forced many turnovers and been in the top 10 in the nation in blocked shots. In this video, you'll get a look at how practice is structured and the beginnings of the organized chaos defense.

Philosophy

In a whiteboard diagram breakdown, Coach D'Antoni walks through his organized chaos defense, describing what the foundations of his defensive philosophy are and how they play into the pressure defense. By forcing the ball handler to one side of the floor, his teams have limited scoring opportunities and stopped the offense before it even starts.

D'Antoni draws up his alignment and placement of both off-ball and on-ball defenders, depending on where the offense sets up. This defense thrives on applying pressure and isolating the ball handler to one side of the floor. In order to do that, switching 1-4 or 1-5 is imperative to keeping the ball on one side of the floor. This is a defense your players will love to play, as it leads to easy transition buckets.

Fundamental Drills

Every defense begins with the basics. On the court, Coach D'Antoni demonstrates proper closeout technique along with how to funnel the ball handler towards the baseline after your closeout. 1v1 defense is a point of emphasis in this style of play. D'Antoni uses a 1v1 run and slide drill to teach players how to sprint and get ahead of the ball handler to cut them off.

After breaking into guard and post groups, Coach D'Antoni builds his team's 1v1 defense through live play. From each wing to the middle of the floor, players battle it out and focus on walling up to prevent an easy layup.

Team Defense Drills

D'Antoni puts his players in game-like situations right away in practice. In 3-on-4, players fly around and closeout to the open shooter. If your defenders don't get to the open man, the offense will be able to create an easy scoring opportunity and prevent your team from getting down the floor in transition.

In 5v5 shell drill, Coach D'Antoni teaches how to defend ball screens by switching and having off-ball defenders be in good help-side to be able to jump and switch to prevent an easy drive to the basket. Placing your post player in the paint will also help prevent rolls to the basket and easy buckets around the rim.

Rounding out this on-court video is a full court defense that is an extension of Marshall's half court approach. Pressuring and influencing the basketball to one side of the floor, 94 feet away from the basket, is how this defense starts and sets the tone for how the game will be played!

Coach D'Antoni delivers the basis of his organized chaos defensive system - shrinking the court in half and forcing to one side of the floor! Your players will love to pressure the ball and get easy buckets off of turnovers. This is a must-see if you are looking to add a pressure defensive system to your program.
