Nellie Ball is an offensive strategy in basketball developed by NBA head coach Don "Nellie" Nelson. It is a fast-paced run-and-gun offense relying on smaller, more athletic players who can create mismatches by outrunning their opponents. A true center is usually not needed to run this type of offense. A large volume of three-point attempts is also a feature of Nellie Ball. This offense is most effective against teams that do not have the athleticism or shooting ability to keep up with the fast pace.
