When Joe Johnson was officially introduced as a Net on Friday, he said they are already the top team in New York. When Gerald Wallace was given an opportunity to voice his opinion on the subject yesterday during a conference call to announce his re-signing with the team, he was much more diplomatic. "No comment," he said. Still, Wallace — the first of the many transactions the Nets completed over the last month when he agreed to a four-year, $40 million deal — is excited about the potential for their first season in Brooklyn.
