For the past 16 months, everything about the Nets has been about one thing: securing a long-term commitment from superstar point guard Deron Williams. Early Tuesday evening, Williams issued his decision between Brooklyn and Dallas, tweeting out a picture of a Brooklyn Nets logo – the one he'll be sporting this fall when he leads the Nets out onto the court against whoever their opponent is in their first game at the brand new Barclays Center. Now, the question turns from who will be running the show for the Nets to who will be filling out their roster, something Nets general manager Billy King began in earnest when free agency started at 12:01 Sunday morning.
