For most NBA prospects, the goal is to get drafted as high as possible. No breaking news there.
But in order to maximize your draft stock, the player has to know the best time to sell. The decision to hold or fold could be the difference between a few million dollars a year.
Realistically, nobody should criticize a college athlete's decision to return to school. Everyone's values are different. Some love the experience and comradeship. Others wants the education. Some just may not be ready from a mental perspective to make the jump.
These are all perfectly good reasons to return to school.
But if we're talking about draft stock and maximizing your value as a young prospect, leaving early might be the move to make. Risking injury or being nitpicked could really damage one's stock, which could cost millions by the time the next draft rolls around.
These players might have been better off selling high, rather than holding on with uncertain futures.
