Sooner rather than later, Mark Cuban will give Williams a call. But King said he isn't concerned. "Because that's the process, that Mark Cuban will call him. End of day, he's going to play here or he's going to play some place else. I think we've done everything, prepared everything. He's got a great building. So everything is mapped out. He sees what we have. He sees what they have. And he's got to make a decision. ...It doesn't worry me, because we're prepared. We've done our work and the ultimate goal is to have him playing, opening the Barclays Center next season. And we haven't wavered on that, but he's got to make the decision that's best for him and his family."
