I want to preface this article with this statement: The 2-3 zone defense should not be allowed in youth basketball.
Instead of listing the reasons why in this article, I encourage you to check out Tyler Coston’s article on the subject which has most of them covered in my opinion.
The 2-3 zone is the most common zone used in the half-court. For better or worse, it’s used by teams of all ages at all levels. So it’s imperative that all coaches are prepared for when their team will face it.
