What does it all mean?

[DrMav]

As a basketball fan, and a European, I couldn’t ask for anything else. What it means for Dallas will ultimately depend on whether he follows in Dirk‘s footsteps and decides to stay in Dallas for the long haul. I have my doubts; Luka seems to cherish the limelight.

All the Mavs organization can do is constantly work to put a competitive team around him. 

Dallas isn't LA or NYK, but it is definitely in the 2nd tier of markets offering natural exposure based on size so it should be easy enough to market him nationally and globally.

I hope that if the things above can be taken care of, another factor that I hope helps keep him here is the relationship he is building with Dirk and seeing how much the Big German is loved by the Dallas community.
