Sleepers, breakouts and busts for the 2025-26 fantasy season: Castle, Sarr, Porter Jr., Murphy III and Buzelis offer high upside as sleepers, with Castle perched outside the top 100 but ready to contribute across points, dimes, and boards. Breakouts like Miller, Flagg, Giddey, Wells, and Ware carry league-winning potential as their roles loom larger. Busts include George, Morant, Zubac, Claxton and VanVleet, where durability, minutes, and surrounding talent may cap upside.
