The New Jersey Nets already view Mark Cuban and the Mavericks as serious threats for Deron Williams’ services this summer, and DWill’s comments about how much he likes to play in his hometown of Dallas probably won’t help them sleep any easier at night. From the Star-Ledger: “Nets fans who worry that point guard Deron Williams might walk as a free agent this summer and sign with his hometown Dallas Mavericks won’t get any reassurance from Williams’ comments after the Nets’ practice Monday at Southern Methodist University. ‘I always like playing here,’ Williams said when asked about his thoughts on playing in Dallas’ American Airlines Center, where the Nets will take on the Mavericks tonight. ‘It’s probably my favorite (arena) to play in. I just enjoy playing here — I enjoy playing in front of my friends, family. It’s always good they get the chance to come and see me play.’ Williams could play in front of his family and friends 41 times a year if he signs with the Mavericks this summer, and Nets coach Avery Johnson admitted he realizes that is a very real possibility. [...] Williams was asked whether he likes the arena itself, or just the idea of playing home. ‘Home,’ he said. ‘(And) I just like the arena. I think it’s a good shooting background. I just enjoy playing here. Fans — the fans are great. It’s always good when arenas have a lot of energy. Ours (the Prudential Center) doesn’t have too much energy.’”
