The only wild card is (Deron) Williams’ unpredictable personality, but Nets officials — GM Billy King chief among them — who committed to four years of Joe Johnson at a $90 million price tag should have a good enough feel for that by now. Though a person close to Williams said Monday night the point guard has been waffling lately on the decision between Brooklyn and Dallas — “He changes every day,” the person said — it’s impossible to believe that the Nets would’ve brought Johnson on board at that price without a wink and a nod from Williams that he was going to Brooklyn, too.

“Never has there been a more wasted trip,” one industry source said of a meeting earlier in the day between the Mavs and Williams. Evidently, Mavs owner Mark Cuban felt the same way, because he didn’t even attend.
