I did a Google search on what players have declared. Here's what came up in AI.
Several college players have declared for the 2025 NBA draft, including underclassmen like Cooper Flagg (Duke), Dylan Harper (Rutgers), Liam McNeeley (UConn), Asa Newell (Georgia), and Kon Knueppel (Duke). These players, along with others, have the option to withdraw their names from the draft and return to college if they choose to do so. The deadline to withdraw and retain college eligibility is April 26.
So I guess AI thinks Flagg already declared.
