Next Star program
The Next Star Program is designed to provide young elite overseas players, mainly Americans, with a professional option immediately out of secondary school. Each team receives one additional import roster slot intended to provide a "Next Star" slot. Contracts are two-year contracts with the NBL which allows players to move between clubs between seasons.
