Controversy with National Superior Basketball
After his departing from the Czech national league, Diaz announced that he was interested in including his name to the list of players in the Puerto Rican BSN draft. He was involved in a movement that was trying to convince the team owners of the league to avoid the implementation of a salary cap to first-year players.

However, the team owners decided to put in cap on salary of twenty five thousand dollars, which led Diaz to remove his name from the list of players. This led former owner Miguel Mercado to create a movement inciting first-year players to withdraw their names from the draft; the controversy reached a conclusion, when Mercado and the league reached an agreement. Diaz announced that he was going to skip participation in any league, and continued his participation in the Clippers Summer League team.
