DWill is taking a wait-and-see approach to his new squad, saying he’ll only consider signing an extension once they prove they can build a winning product around him. From the Star-Ledger: “It wasn’t that I was unhappy, I was just shocked,’ Williams said. ‘It was very unexpected. When you don’t hear any rumors than all of a sudden you’re getting treatment with your teammates and you learn you just got traded, there’s an initial shock. Just didn’t know what to think. I’d be lying if I didn’t say I wasn’t a little nervous when I heard I was going to a team that’s 17-40.’ For Williams, on his first official day as a Net, there was still some uncertainty. Most importantly, despite his enthusiasm, Williams stopped short of saying he would sign a contract extension with the Nets — the key to keeping him with the team long enough to spearhead its move to a new arena in Brooklyn following the 2011-12 season. Williams will become a free agent after next season if he doesn’t re-sign, making the Nets a temporary renter. ‘I can’t really give any assurances, or say that I’ll be here,’ Williams said. ‘I don’t know what the future holds, I look forward to the possibility of it (signing an extension), it’s definitely a strong possibility. It all depends on how the next year goes, (the collective bargaining agreement), the type of moves we make and the people we bring into this organization.’”
