The AP reports: The New Jersey fans who showed up to thank Jason Kidd at the beginning were thanking Mark Cuban by the end. Cuban signed off on the trade that sent Devin Harris to New Jersey—a deal that looks better for the Nets all the time. Harris dominated his former team with 41 points, helping the Nets ruin Kidd’s return with a 121-97 victory over the Mavericks on Friday night. Harris added a season-high 13 assists in thoroughly outplaying Kidd, who spent 6 1/2 years in New Jersey before the Nets dealt him to Dallas last February for a package highlighted by Harris, who had his second 40-point game during a breakout season… Vince Carter added 34 points, 10 rebounds and six assists for the Nets, who improved to just 5-8 at home. Yi Jianlian had 16 points and 10 rebounds. The Nets were 14-of-26 from 3-point range, with Harris hitting five and Carter making four… Dirk Nowitzki had 24 points and Jason Terry added 23 for the Mavs.
