One of the best training techniques to develop basketball instincts.
One of the most underutilized.
In it’s basic form, it teaches the offense(two players) how to read the defense, how to move the defender(with feints and look-aways), how to pass without telegraphing, how to move without the ball, and it teaches the individual defender how to read the passer, how to properly space, and how to dictate to the offense with feints.
Can be modified to involve perimeter or post skills.
Can be incorporated to advanced drills (eg. asymmetric drills like 5-on-4) to focus on team defense or offense.
