For Sasha Vujacic, playing in Europe makes sense.
Anadolu Efes is one of the traditional powers of the Turkish league, a regular part of the EuroLeague. It’s a team that has missed getting any title the last two seasons (domestic or international) and they are motivated to change that. Vujacic could be part of that.
For star players, there is risk in heading overseas. For guys like Vujacic, it makes sense. He was traded to the New Jersey Nets in a salary dump by the Lakers, and the Nets have no intention of bringing him back as his deal expired. He could have found work somewhere in the NBA at a reduced salary (he made $5.5 million last season) but he runs a risk of where and for how much. Europe is a sure thing for him — he will make less but he knows he will get minutes and a good salary (probably not far off what he would make in the NBA).
And he knows in Europe there will be a season.
For guys in Vujacic’s shoes, if there is a good deal to be had from a European team, it makes sense to jump at it.
