He's not under contract for next season. He's currently in season and left to do the Hoop Summit. He can leave for the NBA with no buyout/agreement necessary.Does the NBA have agreements w/the Euro leagues to honor contracts? I assume so, since we regularly hear about contract buyouts. Don't remember hearing similar things happening in the past. Even college teams have been buying out contracts in Europe, though I doubt a specific agreement has ever been agreed by the NCAA- probably just to avoid lawsuits...
