can you go back to college after declaring for the nba draft
A player who declares for the draft will lose his college eligibility, even if he is not drafted, if he signs with any agent. Before 2016, the NCAA only allowed a player to enter the draft once without losing eligibility, but current NCAA rules now allow players to declare for and withdraw from multiple drafts while retaining college eligibility. The CBA allows a player to withdraw twice.
