Moneyball is a bit of an old-school concept at this point that has seemed to be left in the dustpan of history and Hollywood, with the movie coming up on its 15th anniversary next year, and it being even longer since the system has actually been successful. The novel approach to team management popularized and most successfully deployed by the Oakland Athletics in the MLB in the early 2000s has been utilized to a much lesser extent and received much lesser results in most other major American sports leagues. One sports league in particular that has been inhospitable to the strategy has been the NBA. In an NBA dominated by huge contracts, mega-stars, and super teams, it would make sense that if it could work, some creative-thinking GM would have succeeded in actually utilizing it, but so far (unless you count the current Oklahoma City Thunder), we haven’t seen any GM succeed in implementing the system.
