"It could be this June. Rubio has made it clear that he would like to enter the 2009 draft, according to sources close to the situation. The 18-year-old Rubio is draft-eligible because he will turn 19 before the end of 2009.
But it's not that easy. Rubio has a complicated, multimillion-dollar contract buyout with his Spanish team, DKV Joventut Barcelona. NBA teams are allowed to contribute a maximum of $500,000 to buy out the contract of a foreign player. That means if Rubio seeks to leave Joventut, he could be forced to use most of the money from his first NBA contract to pay for the buyout."
