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.

Cooper Flagg headlines a deep 2025-26 rookie class, with Ace Bailey, Kon Knueppel, Dylan Harper, and Khaman Maluach poised for immediate fantasy impact. Flagg is projected to start for Dallas and contribute across points, rebounds, assists and defensive stats, while Jazz, Hornets, Spurs and Suns lean on rookies for early workload. Knueppel and Bailey offer reliable shooting and scoring floor, Harper carries exciting upside despite potential early limitations, and Maluach is a high-risk, high-reward rim protector with room to grow.
