Vujacic is no stranger to the European experience as the Slovenian played professionally in Italy before being made a first round pick by the Los Angeles Lakers in 2004 so this move isn't exactly surprising, especially considering he was set to become a free agent as soon as the NBA lockout ends.
What this means for Vujacic's future in the NBA remains to be seen, however, as SB Nation's Nets blog Nets Daily succinctly describes.
Under the old Collective Bargaining Agreement, the Nets could have retained (or renounced) Vujacic's Bird Rights while he played in Europe. Like everything else, whether that provision is continued, eliminated or changed remains to be seen.
If Williams ever ends up in Turkey, by the way, he'll be the third Nets player to do so as draft pick Bojan Bogdanovic also signed in the European country earlier this summer.
